Python implementation of the [Rx schema and validation system](

Fork of [pyrx]( with added error messages. Most of the readme is also taken from there, just with updated usage instuctions.

"required": {
"a": "//str",
"b": "//int",
"optional": {
"c": "//bool",

schema = rx.make_schema(schema_src)

schema.check({"a": "a string", "b": 2}).valid # returns True
schema.check({"a": "a string", "b": "another string"}).valid # returns False
schema.check({"a": "a string", "b": "another string"}).message # returns an error message
