Trait TryToString

pub trait TryToString {
    // Required method
    fn try_to_string(&self) -> Result<String, Error>;
}

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 try_to_string(&self) -> Result<String, Error>

Converts the given value to a String.

Examples

Basic usage:

use rune::alloc::String;
use rune::alloc::prelude::*;

let i = 5;
let five = String::try_from("5")?;

assert_eq!(five, i.try_to_string()?);
