itoa

This crate provides a fast conversion of integer primitives to decimal strings. The implementation comes straight from libcore but avoids the performance penalty of going through core::fmt::Formatter.

See also ryu for printing floating point primitives.

Version requirement: rustc 1.36+

[dependencies]
itoa = "1.0"

Example

fn main() {
    let mut buffer = itoa::Buffer::new();
    let printed = buffer.format(128u64);
    assert_eq!(printed, "128");
}

Performance (lower is better)
