Astring exposes an alternative
String
module for OCaml. This module tries to balance minimality and
expressiveness for basic, index-free, string processing and provides types and
functions for substrings, string sets and string maps.
Remaining compatible with the OCaml String
module is a non-goal. The
String
module exposed by Astring has exception safe functions, removes
deprecated and rarely used functions, alters some signatures and names, adds a
few missing functions and fully exploits OCaml's newfound string immutability.
