+This crate provides a fast conversion of integer primitives to decimal strings.

+penalty of going through [`core::fmt::Formatter`].
+
+See also [`zmij`] for printing floating point primitives.

+
+## 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.
