Fast function for printing integer primitives to a decimal string
APACHE-2.0 License
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.
