Crate rex_regex

Functions

compile	Optimize and compile a regular expression into a representation that can be directly used for matching with match_re().
match_re	Match a regular expression compiled with compile() against a string. Returns a tuple of a boolean (whether there was a match or partial match) and a vector of (position, length) tuples for all submatches, where the first element describes the match by the whole regular expression.
match_re_str	Parse, compile, and match a regular expression. Not recommended for repeated use, as the regular expression will be compiled every time. Use compile() and match_re() to make this more efficient (about 3x faster).
render_graph	Render the state machine generated from re as graphviz dot input. The result can be pasted into visualize.sh, which renders a PNG image from it.
substring	Easily take a substring from a match tuple.
