ASDF-flavoured YAML document model, parser and emitter
Documentation

ASDF-flavoured YAML: document model, parser and emitter.

ASDF stores its tree as a YAML 1.1 document with three requirements that general-purpose Rust YAML crates do not currently meet together:

  • Tags are the type system. !core/ndarray-1.1.0 is what makes a mapping an array, so tags must survive parsing and be re-emitted.
  • Anchors and aliases are load-bearing. Files in the standard's own reference corpus share nodes through aliases, and a round trip must not silently duplicate or drop them.
  • Scalar style carries meaning. A quoted "123" is a string where an unquoted 123 is an integer.

This crate builds on saphyr-parser's event stream, which surfaces tags, anchor ids and styles, and adds the document model and emitter on top.
