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());

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.
