Function format_buf_args

pub fn format_buf_args<'a>(
    buf: &'a mut [u8],
    arg: FmtArguments<'_>,
) -> Result<&'a str, FmtError> 

Returns a formatted str slice backed by a buffer, non-allocating.

See also the slightly more convenient to use format_buf! macro.

Example

let mut buf = [0u8; 64];
let s = format_buf_args(&mut buf, format_args!["Test: {} {}", "foo", 42]);
assert_eq!(Ok("Test: foo 42"), s);

Features

Makes use of the unsafe_str feature if enabled.
