NAME

Data::ULID::XS - XS backend for ULID generation

SYNOPSIS

  use Data::ULID::XS qw(ulid binary_ulid);

  # use like Data::ULID

DESCRIPTION

This module replaces some parts of Data::ULID that are performance-critical with XS counterparts. Its interface is the same as Data::ULID, but you get free XS speedups.

Beta quality: while this module works well in general cases, it may also contain errors common to C code like memory leaks or access violations. Please do report if you encounter any problems.

FUNCTIONS

Same as Data::ULID. All functions should work exactly the same, but ulid and binary_ulid called with no arguments are reimplemented in XS.

BENCHMARK
