Trait IntoWasmAbi 

pub trait IntoWasmAbi: WasmDescribe {
    type Abi: WasmAbi;

    // Required method
    fn into_abi(self) -> Self::Abi;
}

A trait for anything that can be converted into a type that can cross the Wasm ABI directly, eg u32 or f64.

This is the opposite operation as FromWasmAbi and Ref[Mut]FromWasmAbi.

⚠️ Unstable

This is part of the internal convert module, no stability guarantees are provided. Use at your own risk. See its documentation for more details.

Required Associated Types

type Abi: WasmAbi

The Wasm ABI type that this converts into when crossing the ABI boundary.

Required Methods

fn into_abi(self) -> Self::Abi

Convert self into Self::Abi so that it can be sent across the wasm ABI boundary.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

'static closures can be passed by value to JS, transferring ownership.

This is useful for one-shot callbacks where you want JS to own the closure. The closure will be cleaned up by JS GC (if weak references are supported) or will leak (if weak references are not supported).

Example

#[wasm_bindgen]
extern "C" {
    fn set_one_shot_callback(cb: Closure<dyn FnMut()>);
}

let cb = Closure::new(|| { /* ... */ });
set_one_shot_callback(cb);  // Ownership transferred to JS
// No need to store or forget the closure
