fp-bindgen
[fp-bindgen](https://github.com/fiberplane/fp-bindgen), by
[fibreplane](/fibreplane/), can be used for creating wasm bindings.
See also: [wit-bindgen](/wit-bindgen/), [witx-bindgen](/witx/) and
[wasm-bindgen](/wasm-bindgen/).
Wasmer Only?
Looks like it only works with [wasmer](/wasmer/), and not
[wasmtime](/wasmtime/).
Can Use Rust For Binding Definition
> fp-bindgen is opinionated towards Rust. It uses Rust data structures and
function signatures as its "protocol format", enabling tight integration with
existing crates from the Rust ecosystem.
use fp_bindgen::prelude::Serializable;
#[derive(Serializable)]
#[fp(rust_module = "my_crate::prelude")]
pub struct MyStruct {
pub foo: i32,
pub bar_qux: String,
}
> In this example, MyStruct has a double function: it acts both as a type
definition for the protocol (through fp-bindgen's Serializable trait), which
can still be used for generating a TypeScript type definition, for instance.
And it acts as a type that can be directly used by the Rust Wasmer runtime,
under the assumption the runtime can import it from my_crate::prelude.
