# 1.0.0[−][src]Trait std::string::ToString

    pub trait ToString {
        fn to_string(&self) -> String;
    }

A trait for converting a value to a `String`.

This trait is automatically implemented for any type which implements the `Display` trait. As such, `ToString` shouldn't be implemented directly: `Display` should be implemented instead, and you get the `ToString` implementation for free.

## Required methods

### `fn to_string(&self) -> String`

Converts the given value to a `String`.

# Examples

Basic usage:

    let i = 5;
    let five = String::from("5");

    assert_eq!(five, i.to_string());Run

## Implementors

### `impl ToString for str`[src]

#### `fn to_string(&self) -> String`[src]

### `impl ToString for String`[src]

#### `fn to_string(&self) -> String`[src]

### `impl<'a> ToString for Cow<'a, str>`[src]

#### `fn to_string(&self) -> String`[src]

### `impl<T> ToString for T where
T: Display + ?Sized,` [src]

# Panics

In this implementation, the `to_string` method panics if the `Display` implementation returns an error. This indicates an incorrect `Display` implementation since `fmt::Write for String` never returns an error itself.

## 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`)
