URI Parsing is a library for building composable URI parsers using ppx_typed_fields.
See the Bonsai Guide chapter on urls. This library contains the "typed" parsing/unparsing module for URL Var. The reason that this library exists as a separate library is that URL Var has a JavaScript browser dependency which makes it unable to run outside of a JavaScript browser context.
Splitting off the parsing/unparsing logic allows it to be used on native OCaml.
