Module combinator

General purpose combinators

Structs

• ParserIterator
  Main structure associated to the iterator function.

Functions

• all_consuming
  Succeeds if all the input has been consumed by its child parser.
• complete
  Transforms Incomplete into Error.
• cond
  Calls the parser if the condition is met.
• consumed
  if the child parser was successful, return the consumed input with the output as a tuple. Functions similarly to recognize except it returns the parser output as well.
• cut
  Transforms an Err::Error (recoverable) to Err::Failure (unrecoverable)
• eof
  returns its input if it is at the end of input data
• fail
  A parser which always fails.
• flat_map
  Creates a new parser from the output of the first parser, then apply that parser over the rest of the input.
• into
  automatically converts the child parser’s result to another type
• iterator
  Creates an iterator from input data and a parser.
• map
  Maps a function on the result of a parser.
• map_opt
  Applies a function returning an Option over the result of a parser.
• map_parser
  Applies a parser over the result of another one.
• map_res
  Applies a function returning a Result over the result of a parser.
• not
  Succeeds if the child parser returns an error.
• opt
  Optional parser, will return None on Err::Error.
• peek
  Tries to apply its parser without consuming the input.
• recognize
  If the child parser was successful, return the consumed input as produced value.
• rest
  Return the remaining input.
• rest_len
  Return the length of the remaining input.
• success
  a parser which always succeeds with given value without consuming any input.
• value
  Returns the provided value if the child parser succeeds.
• verify
  Returns the result of the child parser if it satisfies a verification function.
