Hi team, For wit IDL, is that possible also to include &self in functions of interface for Rust lang? As I'd like to share datas between functions in the WIT.

Are you referring to Wasm guest exports? There is no "self" value associated with those implementations.

You can export resource types from your component, in which case each of the non-static methods will get a &self parameter in the wit-bindgen-generated Rust bindings.
