Medium level API functions
compile
:: CompOption(summed together)
-> ExecOption(summed together)
-> ByteStringThe regular expression to compile
-> IO (Either (MatchOffset, String) Regex)Returns: the compiled regular expression
Compiles a regular expression
execute
:: RegexCompiled regular expression
-> ByteStringString to match against
-> IO (Either WrapError (Maybe (Array Int (MatchOffset, MatchLength))))Returns: Nothing if the regex did not match the string, or: Just an array of (offset,length) pairs where index 0 is whole match, and the rest are the captured subexpressions.

Matches a regular expression against a buffer, returning the buffer indicies of the match, and any submatches

| Matches a regular expression against a string

regexec
:: RegexCompiled regular expression
-> ByteStringString to match against
-> IO (Either WrapError (Maybe (ByteString, ByteString, ByteString, [ByteString])))
