A minimal, low-copy, very opinionated conversion layer from the kdl library to serde.
This is mainly intended for Dialga, my crate for a Caves of Qud-like blueprint instatiation system, which in turn is intended for Palkia.
There were shortcomings for me with all the extant KDL libraries for Rust:
- Knuffel is very powerful, but rolls its own deserialization system and macros instead of using Serde. (Which is appropriate for what it's trying to do, granted; KDL doesn't map all too well to Serde's data model.) It stores the AST in memory, but requires also storing the span of text it was parsed from, and I wanted just pure ASTs sitting around.
- Kaydle is a KDL library that uses Serde, but isn't as feature-complete as Knuffel and doesn't store the AST in memory.
Call knurdy::deserialize_node, or directly use the KdlNodeDeser.
