Expand description

Parser combinator library.

Macros§

byte_map: Helper to create a parser::byte_lut parser using match-like syntax.
literal_map: Helper to create a Leaf parser matching string literals using match-like syntax.
parsable_enum: Helper to define a Parseable fieldless unit-only enum.
parse_tree: Helper to define a custom Parser using a match inspired parse tree syntax.

ErrToken: ZST used to ensure that Parser implementations push errors to ParseState.
ParseState: Per-parse shared state.
ParserIterator: An iterator that lazily parses the input using the provided parser.
ParserMatchesIterator: An iterator which returns successful parse outputs only, skipping over errors.

byte: Leaf parser that consumes a single byte.
byte_lut: Leaf parser that consumes a single byte and maps it using a lookup table.
byte_range: Leaf parser that consumes a single byte in the supplied range.
constant: Leaf parser that consumes no input and always succeeds, returning the provided value.
digit: Leaf parser for single digits.
eof: Leaf parser which matches the end of the input.
eol: Leaf parser which matches newlines or the end of the input.
from_leaf_fn: Coerces the provided function/closure into a Leaf parser.
from_parser_fn: Parser which delegates to the provided function/closure.
i8: Leaf parser for i8 values.
i16: Leaf parser for i16 values.
i32: Leaf parser for i32 values.
i64: Leaf parser for i64 values.
i128: Leaf parser for i128 values.
noop: Leaf parser that consumes no input and always succeeds, returning ().
number_range: Leaf parser for numbers in the supplied range.
one_of: Parser which tries a list of parsers in order until one succeeds.
take_while: Leaf parser for substrings matching the provided function.
take_while1: Leaf parser for non-empty substrings matching the provided function.
u8: Leaf parser for u8 values.
u16: Leaf parser for u16 values.
u32: Leaf parser for u32 values.
u64: Leaf parser for u64 values.
u128: Leaf parser for u128 values.
