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

    pub trait ToString {
        pub 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

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

Converts the given value to a `String`.

# Examples

Basic usage:

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

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

# 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.
