   9 This crate provides a fast conversion of integer primitives to decimal strings.
  10 The implementation comes straight from [libcore] but avoids the performance
  11 penalty of going through [`core::fmt::Formatter`].
  12
  13 See also [`ryu`] for printing floating point primitives.

  15 *Version requirement: rustc 1.36+*
