Macros§

AnyParser: Parses for any of the supplied parsers and returns the first successful result, or an error if no parser matched.
BetweenParser: Between parser
Context: Parser context
ExactParser: Attempts to parse a specified number of chars or to the EOI and fails otherwise
ExpectParser: Runs a supplied parser, if fails, returns a custom error message
Failure: Failure is a failed parse result
FloatParser: Parses for a float
ForgetParser: “Forgets” the success value type and changes it to ()
IntegerParser: Parses for an integer
LettersParser: Parses for at least one letter
ManyParser: Parses as many times as possible, returns an error if no parsing was successful
MapParser: Maps the result of a parser to a new value
OptionalParser: Tries to parse the given parser, but if it fails, it returns a successful result with a None value
RegexParser: Parses for a given regex pattern
SequenceParser: Parses for a sequence of parsers
SpacesParser: Parses for at least one and as many spaces as possible
StringParser: Parses for a specific target string
Success: Success is a successful parse result
SurelyParser: If an any parser comes across a surely parser and it fails the any parser immediately fails as well

ParserType: The types of parsers
Pos: Enum used to determine the relative position to parse to in the exact parser

ContextParserT: Trait for parsers that can take in a Context and act on it.
Parsers are understood to be pure with static state after initialization. This is important because AnyParser, SequenceParser and likewise parsers store parsers internally as ParserRc<dyn ContextParserT<T>> and thus only make a shallow copy. Parsers that are not pure might and likely will cause unexpected behaviour.
StringParserT: This is a sub-trait of ContextParserT<T>. It’s only function is to abstract away the creation of an initial Context for parsing and acts as “syntax sugar”.
