Function write

pub fn write(output: &mut dyn Write, args: Arguments<'_>) -> Result<(), Error>

Available on crate feature mtls only.

Takes an output stream and an Arguments struct that can be precompiled with the format_args! macro.

The arguments will be formatted according to the specified format string into the output stream provided.

Examples

Basic usage:

use std::fmt;

let mut output = String::new();
fmt::write(&mut output, format_args!("Hello {}!", "world"))
    .expect("Error occurred while trying to write in String");
assert_eq!(output, "Hello world!");

Please note that using write! might be preferable. Example:

use std::fmt::Write;

let mut output = String::new();
write!(&mut output, "Hello {}!", "world")
    .expect("Error occurred while trying to write in String");
assert_eq!(output, "Hello world!");
