Description: API documentation for the Rust `SeekFrom` enum in crate `std`.
Keywords: rust, rustlang, rust-lang, SeekFrom

# 1.0.0[−][src]Enum std::io::SeekFrom

    pub enum SeekFrom {
        Start(u64),
        End(i64),
        Current(i64),
    }

Enumeration of possible methods to seek within an I/O object.

It is used by the `Seek` trait.

## Variants

`Start(u64)`

Sets the offset to the provided number of bytes.

`End(i64)`

Sets the offset to the size of this object plus the specified number of bytes.

It is possible to seek beyond the end of an object, but it's an error to seek before byte 0.

`Current(i64)`

Sets the offset to the current position plus the specified number of bytes.

It is possible to seek beyond the end of an object, but it's an error to seek before byte 0.

## 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`)
