Trait wasmer::FromToNativeWasmType

pub unsafe trait FromToNativeWasmType: Copy where
    Self: Sized, {
    type Native: NativeWasmType;
    pub fn from_native(native: Self::Native) -> Self;
    pub fn to_native(self) -> Self::Native;
}

A trait to convert a Rust value to a WasmNativeType value, or to convert WasmNativeType value to a Rust value.

This trait should ideally be split into two traits: FromNativeWasmType and ToNativeWasmType but it creates a non-negligible complexity in the WasmTypeList implementation.

Associated Types
