Rust Parsing Benchmarks

This repo tries to assess Rust parsing performance.

crate	parser type	action code	integration	input type	precedence climbing	parameterized rules	streaming input
chumsky	combinators	in source	library	`&str`	?	?	?
combine	combiantors	in source	library	`&str`	?	?	?
lalrpop	LR(1)	in grammar	build script	`&str`	No	Yes	No
nom	combinators	in source	library	`&[u8]`, custom	No	Yes	Yes
peg	PEG	in grammar	proc macro (block)	`&str`, `&[T]`, custom	Yes	Yes	No
pest	PEG	external	proc macro (file)	`&str`	Yes	No	No
pom	combiantors	in source	library	`&str`	?	?	?
winnow	combinators	in source	library	`&str`, `&[T]`, custom	No	Yes	Yes
yap	combinators	in source	library	`&str`, `&[T]`, custom	No	Yes	?
