asdf-yaml 0.2.1

//! 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.

#![forbid(unsafe_code)]

// Named so `alloc::` paths can be written directly. The crate links `std`,
// but spelling collection and string types at the narrowest layer that
// defines them keeps a future `no_std` build a small step away.
