Types
data Regex
A compiled regular expression
Instances
type MatchOffset = Int
0 based index from start of source, or (-1) for unused
type MatchLength = Int
non-negative length of a match
data ReturnCode
Instances
type WrapError = (ReturnCode, String)
Miscellaneous
return version of pcre used or Nothing if pcre is not available.
