Struct core::fmt::Error1.0.0 [] [src]

pub struct Error;

The error type which is returned from formatting a message into a stream.

This type does not support transmission of an error other than that an error occurred. Any extra information must be arranged to be transmitted through some other means.

An important thing to remember is that the type fmt::Error should not be confused with std::io::Error or std::error::Error, which you may also have in scope.

Examples

use std::fmt::{self, write};

let mut output = String::new();
match write(&mut output, format_args!("Hello {}!", "world")) {
    Err(fmt::Error) => panic!("An error occurred"),
    _ => (),
}Run
