A trait for anything that can be recovered by-value from the wasm ABI
boundary, eg a Rust
u8 can be recovered from the wasm ABI
This is the by-value variant of the opposite operation as
The wasm ABI type that this converts from when coming back out from the ABI boundary.
This is only safe to call when – and implementations may assume that –
Self::Abi was previously generated by a call to
<Self as IntoWasmAbi>::into_abi() or the moral equivalent in JS.
