Trait wasm_bindgen::convert::RefFromWasmAbi

pub trait RefFromWasmAbi: WasmDescribe {
    type Abi: WasmAbi;
    type Anchor: Deref<Target = Self>;

    // Required method
    unsafe fn ref_from_abi(js: Self::Abi) -> Self::Anchor;
}

A trait for anything that can be recovered as some sort of shared reference from the wasm ABI boundary.

This is the shared reference variant of the opposite operation as IntoWasmAbi.

⚠️ 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 references to Self are recovered from.

type Anchor: Deref<Target = Self>

The type that holds the reference to Self for the duration of the invocation of the function that has an &Self parameter. This is required to ensure that the lifetimes don’t persist beyond one function call, and so that they remain anonymous.

Required Methods

unsafe fn ref_from_abi(js: Self::Abi) -> Self::Anchor

Recover a Self::Anchor from Self::Abi.

Safety

Same as FromWasmAbi::from_abi.

Object Safety

This trait is not object safe.
