# 1.0.0[−]Primitive Type i32

The 32-bit signed integer type.

See also the `std::i32` module.

## Methods

###

`impl i32`

[src]

####

`pub const fn min_value() -> i32`

[src]

Returns the smallest value that can be represented by this integer type.

# Examples

Basic usage:

    assert_eq!(i32::min_value(), -2147483648);Run

####

`pub const fn max_value() -> i32`

[src]

Returns the largest value that can be represented by this integer type.

# Examples

Basic usage:

####

`pub fn from_str_radix(src: &str, radix: u32) -> Result<i32, ParseIntError>`

[src]

Converts a string slice in a given base to an integer.

The string is expected to be an optional `+` or `-` sign followed by digits. Leading and trailing whitespace represent an error. Digits are a subset of these characters, depending on `radix`:

- `0-9`
- `a-z`
- `A-Z`

# Panics

This function panics if `radix` is not in the range from 2 to 36.

# Examples

Basic usage:

    assert_eq!(i32::from_str_radix("A", 16), Ok(10));Run

`pub fn wrapping_div(self, rhs: i32) -> i32`

1.2.0
[src]

Wrapping (modular) division. Computes `self / rhs`, wrapping around at the boundary of the type.

The only case where such wrapping can occur is when one divides `MIN / -1` on a signed type (where `MIN` is the negative minimal value for the type); this is equivalent to `-MIN`, a positive value that is too large to represent in the type. In such a case, this function returns `MIN` itself.

# Panics

This function will panic if `rhs` is 0.

# Examples

Basic usage:

    assert_eq!(100i32.wrapping_div(10), 10);
    assert_eq!((-128i8).wrapping_div(-1), -128);Run

####

`pub fn wrapping_div_euc(self, rhs: i32) -> i32`

[src]

🔬 This is a nightly-only experimental API. (`euclidean_division` #49048)

Wrapping Euclidean division. Computes `self.div_euc(rhs)`, wrapping around at the boundary of the type.

Wrapping will only occur in `MIN / -1` on a signed type (where `MIN` is the negative minimal value for the type). This is equivalent to `-MIN`, a positive value that is too large to represent in the type. In this case, this method returns `MIN` itself.

# Panics

This function will panic if `rhs` is 0.

# Examples

Basic usage:

    #![feature(euclidean_division)]

####

`pub fn wrapping_rem(self, rhs: i32) -> i32`

1.2.0
[src]

Wrapping (modular) remainder. Computes `self % rhs`, wrapping around at the boundary of the type.

Such wrap-around never actually occurs mathematically; implementation artifacts make `x % y` invalid for `MIN / -1` on a signed type (where `MIN` is the negative minimal value). In such a case, this function returns `0`.

# Panics

This function will panic if `rhs` is 0.

# Examples

Basic usage:

    assert_eq!(100i32.wrapping_rem(10), 0);
    assert_eq!((-128i8).wrapping_rem(-1), 0);Run

####

`pub fn wrapping_mod_euc(self, rhs: i32) -> i32`

[src]

🔬 This is a nightly-only experimental API. (`euclidean_division` #49048)

Wrapping Euclidean modulo. Computes `self.mod_euc(rhs)`, wrapping around at the boundary of the type.

Wrapping will only occur in `MIN % -1` on a signed type (where `MIN` is the negative minimal value for the type). In this case, this method returns 0.

# Panics

This function will panic if `rhs` is 0.

# Examples

Basic usage:

    #![feature(euclidean_division)]
    assert_eq!(100i32.wrapping_mod_euc(10), 0);
    assert_eq!((-128i8).wrapping_mod_euc(-1), 0);Run

####

`pub fn wrapping_neg(self) -> i32`

1.2.0
[src]

Wrapping (modular) negation. Computes `-self`, wrapping around at the boundary of the type.

The only case where such wrapping can occur is when one negates `MIN` on a signed type (where `MIN` is the negative minimal value for the type); this is a positive value that is too large to represent in the type. In such a case, this function returns `MIN` itself.

# Examples

Basic usage:

    assert_eq!(100i32.wrapping_neg(), -100);
    assert_eq!(i32::min_value().wrapping_neg(), i32::min_value());Run

####

`pub fn wrapping_shl(self, rhs: u32) -> i32`

1.2.0
[src]

Panic-free bitwise shift-left; yields `self << mask(rhs)`, where `mask` removes any high-order bits of `rhs` that would cause the shift to exceed the bitwidth of the type.

Note that this is not the same as a rotate-left; the RHS of a wrapping shift-left is restricted to the range of the type, rather than the bits shifted out of the LHS being returned to the other end. The primitive integer types all implement a `rotate_left` function, which may be what you want instead.

# Examples

Basic usage:

    assert_eq!((-1i32).wrapping_shl(7), -128);
    assert_eq!((-1i32).wrapping_shl(128), -1);Run

####

`pub fn wrapping_shr(self, rhs: u32) -> i32`

1.2.0
[src]

Panic-free bitwise shift-right; yields `self >> mask(rhs)`, where `mask` removes any high-order bits of `rhs` that would cause the shift to exceed the bitwidth of the type.

Note that this is not the same as a rotate-right; the RHS of a wrapping shift-right is restricted to the range of the type, rather than the bits shifted out of the LHS being returned to the other end. The primitive integer types all implement a `rotate_right` function, which may be what you want instead.

# Examples

Basic usage:

    assert_eq!((-128i32).wrapping_shr(7), -1);
    assert_eq!((-128i16).wrapping_shr(64), -128);Run

####

`pub fn wrapping_abs(self) -> i32`

1.13.0
[src]

Wrapping (modular) absolute value. Computes `self.abs()`, wrapping around at the boundary of the type.

The only case where such wrapping can occur is when one takes the absolute value of the negative minimal value for the type this is a positive value that is too large to represent in the type. In such a case, this function returns `MIN` itself.

# Examples

Basic usage:

    assert_eq!(100i32.wrapping_abs(), 100);
    assert_eq!((-100i32).wrapping_abs(), 100);
    assert_eq!(i32::min_value().wrapping_abs(), i32::min_value());

# Examples

Basic usage:

    use std::i32;

    assert_eq!(2i32.overflowing_neg(), (-2, false));
    assert_eq!(i32::MIN.overflowing_neg(), (i32::MIN, true));Run

`pub fn overflowing_shl(self, rhs: u32) -> (i32, bool)`

1.7.0
[src]

Shifts self left by `rhs` bits.

Returns a tuple of the shifted version of self along with a boolean indicating whether the shift value was larger than or equal to the number of bits. If the shift value is too large, then value is masked (N-1) where N is the number of bits, and this value is then used to perform the shift.

# Examples

Basic usage:

    assert_eq!(0x1i32.overflowing_shl(4), (0x10, false));
    assert_eq!(0x1i32.overflowing_shl(36), (0x10, true));Run

####

1.7.0
[src]

Shifts self right by `rhs` bits.

Returns a tuple of the shifted version of self along with a boolean indicating whether the shift value was larger than or equal to the number of bits. If the shift value is too large, then value is masked (N-1) where N is the number of bits, and this value is then used to perform the shift.

# Examples

Basic usage:

    assert_eq!(0x10i32.overflowing_shr(4), (0x1, false));
    assert_eq!(0x10i32.overflowing_shr(36), (0x1, true));Run

####

`pub fn overflowing_abs(self) -> (i32, bool)`

1.13.0
[src]

Computes the absolute value of `self`.

Returns a tuple of the absolute version of self along with a boolean indicating whether an overflow happened. If self is the minimum value (e.g. i32::MIN for values of type i32), then the minimum value will be returned again and true will be returned for an overflow happening.

# Examples

Basic usage:

    assert_eq!(10i32.overflowing_abs(), (10, false));
    assert_eq!((-10i32).overflowing_abs(), (10, false));
    assert_eq!((i32::min_value()).overflowing_abs(), (i32::min_value(), true));Run

####

`pub fn overflowing_pow(self, exp: u32) -> (i32, bool)`

[src]

🔬 This is a nightly-only experimental API. (`no_panic_pow` #48320)

Raises self to the power of `exp`, using exponentiation by squaring.

Returns a tuple of the exponentiation along with a bool indicating whether an overflow happened.

# Examples

####

`pub fn pow(self, exp: u32) -> i32`

[src]

Raises self to the power of `exp`, using exponentiation by squaring.

# Examples

    assert_eq!(x.pow(5), 32);Run

####

`pub fn div_euc(self, rhs: i32) -> i32`

[src]

🔬 This is a nightly-only experimental API. (`euclidean_division` #49048)

Calculates the quotient of Euclidean division of `self` by `rhs`.

This computes the integer `n` such that `self = n * rhs + self.mod_euc(rhs)`. In other words, the result is `self / rhs` rounded to the integer `n` such that `self >= n * rhs`.

# Panics

This function will panic if `rhs` is 0.

# Examples

Basic usage:

    #![feature(euclidean_division)]
    let a: i32 = 7; // or any other integer type
    let b = 4;

    assert_eq!(a.div_euc(b), 1); // 7 >= 4 * 1
    assert_eq!(a.div_euc(-b), -1); // 7 >= -4 * -1
    assert_eq!((-a).div_euc(b), -2); // -7 >= 4 * -2
    assert_eq!((-a).div_euc(-b), 2); // -7 >= -4 * 2Run

####

`pub fn mod_euc(self, rhs: i32) -> i32`

[src]

🔬 This is a nightly-only experimental API. (`euclidean_division` #49048)

Calculates the remainder `self mod rhs` by Euclidean division.

In particular, the result `n` satisfies `0 <= n < rhs.abs()`.

# Panics

This function will panic if `rhs` is 0.

# Examples

Basic usage:

    #![feature(euclidean_division)]
    let a: i32 = 7; // or any other integer type
    let b = 4;

    assert_eq!(a.mod_euc(b), 3);
    assert_eq!((-a).mod_euc(b), 1);
    assert_eq!(a.mod_euc(-b), 3);
    assert_eq!((-a).mod_euc(-b), 1);Run

####

`pub fn abs(self) -> i32`

[src]

Computes the absolute value of `self`.

# Overflow behavior

The absolute value of `i32::min_value()` cannot be represented as an `i32`, and attempting to calculate it will cause an overflow. This means that code in debug mode will trigger a panic on this case and optimized code will return `i32::min_value()` without a panic.

# Examples

Basic usage:

    assert_eq!(10i32.abs(), 10);
    assert_eq!((-10i32).abs(), 10);Run

####

# Examples

Basic usage:

    assert_eq!(10i32.signum(), 1);
    assert_eq!(0i32.signum(), 0);
    assert_eq!((-10i32).signum(), -1);Run

####

`pub fn is_positive(self) -> bool`

[src]

####

`pub fn is_negative(self) -> bool`

[src]

🔬 This is a nightly-only experimental API. (`int_to_from_bytes` #52963)

Create an integer value from its memory representation as a byte array in native endianness.

As the target platform's native endianness is used, portable code likely wants to use `from_be_bytes` or `from_le_bytes`, as appropriate instead.

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g. `str,u8` or `String,struct:Vec,test`)
