nom by removing the
IResult::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
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
