extism_convert/lib.rs
1//! The [extism-convert](https://crates.io/crates/extism-convert) crate is used by the [Rust SDK](https://crates.io/crates/extism) and [Rust PDK](https://crates.io/crates/extism-pdk) to provide a shared interface for
2//! encoding and decoding values that can be passed to Extism function calls.
3//!
4//! A set of types (Json, Msgpack) that can be used to specify a serde encoding are also provided. These are
5//! similar to [axum extractors](https://docs.rs/axum/latest/axum/extract/index.html#intro) - they are
6//! implemented as a tuple struct with a single field that is meant to be extracted using pattern matching.
