Crate unrest_tmp_synom

Adapted from nom by removing the IPResult::Incomplete variant which:

• we don't need,
• is an unintuitive footgun when working with non-streaming use cases, and
• more than doubles compilation time.

Whitespace handling strategy

As (sy)nom is a parser combinator library, the parsers provided here and that you implement yourself are all made up of successively more primitive parsers, eventually culminating in a small number of fundamental parsers that are implemented in Rust. Among these are punct! and keyword!.

All synom fundamental parsers (those not combined out of other parsers) should be written to skip over leading whitespace in their input. This way, as long as every parser eventually boils down to some combination of fundamental parsers, we get correct whitespace handling at all levels for free.

For our use case, this strategy is a huge improvement in usability, correctness, and compile time over nom's ws! strategy.

Modules

cursor	This module defines a cheaply-copyable cursor into a TokenStream's data.
delimited
span
tokens	Discrete tokens that can be parsed out by synom.

Macros

alt	Run a series of parsers, returning the result of the first one which succeeds.
call	Invoke the given parser function with the passed in arguments.
cond	Conditionally execute the given parser.
cond_reduce	Fail to parse if condition is false, otherwise parse the given parser.
do_parse	Run a series of parsers, one after another, optionally assigning the results a name. Fail if any of the parsers fails.
input_end
many0	Parse zero or more values using the given parser.
map	Transform the result of a parser by applying a function or closure.
named	Define a function from a parser combination.
not	Parses successfully if the given parser fails to parse. Does not consume any of the input.
peek	Parse a value without consuming it from the input data.
switch	Pattern-match the result of a parser to select which other parser to run.
terminated	Parse two things, returning the value of the first.
tuple	Run a series of parsers and produce all of the results in a tuple.
value	Produce the given value without parsing anything. Useful as an argument to switch!.
