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