Traits

ChoiceParser

ChoiceParser represents a parser which may parse one of several different choices depending on the input.

Functions

and_then	Equivalent to p.and_then(f).
any	Parses any token.
between	Parses open followed by parser followed by close. Returns the value of parser.
chainl1	Parses p 1 or more times separated by op. The value returned is the one produced by the left associative application of the function returned by the parser op.
chainr1	Parses p one or more times separated by op. The value returned is the one produced by the right associative application of the function returned by op.
choice	Takes a tuple, a slice or an array of parsers and tries to apply them each in order. Fails if all the parsers fails or if an applied parser consumes input before failing.
count	Parses parser from zero up to count times.
count_min_max	Parses parser from min to max times (including min and max).
env_parser	Constructs a parser out of an environment and a function which needs the given environment to do the parsing. This is commonly useful to allow multiple parsers to share some environment while still allowing the parsers to be written in separate functions.
eof	Succeeds only if the stream is at end of input, fails otherwise.
expected	Equivalent to p.expected(info).
flat_map	Equivalent to p.flat_map(f).
look_ahead	look_ahead(p) acts as p but doesn't consume input on success.
many	Parses p zero or more times returning a collection with the values from p.
many1	Parses p one or more times returning a collection with the values from p.
map	Equivalent to p.map(f).
message	Equivalent to p1.message(msg).
none_of	Extract one token and succeeds if it is not part of tokens.
not_followed_by	Succeeds only if parser fails. Never consumes any input.
one_of	Extract one token and succeeds if it is part of tokens.
optional	Parses parser and outputs Some(value) if it succeeds, None if it fails without consuming any input. Fails if parser fails after having consumed some input.
or	Equivalent to p1.or(p2).
parser	Wraps a function, turning it into a parser.
position	Parser which just returns the current position in the stream.
recognize	Constructs a parser which returns the tokens parsed by parser accumulated in F: FromIterator<P::Input::Item> instead of P::Output.
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.
sep_by	Parses parser zero or more time separated by separator, returning a collection with the values from p.
sep_by1	Parses parser one or more time separated by separator, returning a collection with the values from p.
sep_end_by	Parses parser zero or more times separated and ended by separator, returning a collection with the values from p.
sep_end_by1	Parses parser one or more times separated and ended by separator, returning a collection with the values from p.
skip
skip_count	Parses parser from zero up to count times skipping the output of parser.
skip_count_min_max	Parses parser from min to max times (including min and max) skipping the output of parser.
skip_many	Parses p zero or more times ignoring the result.
skip_many1	Parses p one or more times ignoring the result.
then	Equivalent to p.then(f).
token	Parses a character and succeeds if the character is equal to c.
tokens	Parses multiple tokens.
try	try(p) behaves as p except it acts as if the parser hadn't consumed any input if p fails after consuming input.
unexpected	Always fails with message as an unexpected error. Never consumes any input.
value	Always returns the value v without consuming any input.
with	Equivalent to p1.with(p2).
