1.0.0[−][src]Function alloc::fmt::write
pub fn write(output: &mut dyn Write, args: Arguments) -> Result<(), Error>
The write
function 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!");
