Structs§

any: Parses any token.
eof: Succeeds only if the stream is at end of input, fails otherwise.
none_of: Extract one token and succeeds if it is not part of tokens.
one_of: Extract one token and succeeds if it is part of tokens.
position: Parser which just returns the current position in the stream.
produce: Always returns the value produced by calling f.
satisfy: Parses a token and succeeds depending on the result of predicate.
satisfy_map: Parses a token and passes it to predicate. If predicate returns Some the parser succeeds and returns the value inside the Option. If predicate returns None the parser fails without consuming any input.

tokens: Parses multiple tokens.
tokens_cmp: Parses multiple tokens.
value: Always returns the value v without consuming any input.
