Release 1.0.18
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 zmij for printing floating point primitives.
[dependencies] itoa = "1.0"
fn main() { let mut buffer = itoa::Buffer::new(); let printed = buffer.format(128u64); assert_eq!(printed, "128"); }
The itoa-benchmark compares this library and other Rust integer formatting implementations across a range of integer sizes. The vertical axis in this chart shows nanoseconds taken by a single execution of itoa::Buffer::new().format(value) so a lower result indicates a faster library.
