futures-await-syn
This crate is a temporary fork of dtolnay/syn. The syn
repository
isn't ready for publication yet but we'd like to publish the futures-await
crate. This is a temporary fork that will only be maintained for the
futures-await
crate and it will be unmaintained as soon as syn
is
published upstream.

lib.rs
:
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.
