yaml-peg
A YAML 1.2 parser using a greedy parsing algorithm with PEG atoms. Support anchors, directives, positions, tags, serde, and no-std.
Inspired from yaml-rust
and serde-yaml
.
This parser is not ensure about YAML spec but almost functions are well-implemented. The buffer reader has also not yet been implemented, but the chunks can be read by the sub-parsers.
The anchors can be visited by the loader after parsing.
use ;
let doc = "
---
name: Bob
married: true
age: 46
";
let root = parse.unwrap;
assert_eq!;
See the API doc for more information.

Support
serde
to help you serialize and deserialize a specific type. (as well as the non-cyclic anchors)use Deserialize; use from_str; let doc = " --- name: Bob married: true age: 46 "; // Return Vec<Member>, use `.remove(0)` to get the first one let officer = .unwrap.remove; assert_eq!; assert!; assert_eq!;
