Decrusting the serde crate

Jon Gjengset performs a deep dive into the design, traits, and data model of Rust's serde serialization library.

In this stream, we peel back the crust on the serde crate — github.com/serde-rs/serde/ — and explore its interface, structure, and mechanisms. We talk about Serialize/Deserialize, Serializer/Deserializer, and the Visitor trait. We also get into the serde data model, and in particular the separation between data types, serde data values, and data formats. For more details about serde, see serde.rs/.
