[−][src]Enum sp_runtime_interface::wasm::WrappedFFIValue

pub enum WrappedFFIValue<T, O = ()> {
    Wrapped(T),
    WrappedAndOwned(T, O),
}

Represents a wrapped ffi value.

It is either the ffi value itself or the ffi value plus some other owned value. By providing support for storing another owned value besides the actual ffi value certain performance optimizations can be applied. For example using the pointer to a Vec<u8>, while using the pointer to a SCALE encoded Vec<u8> that is stored in this wrapper for any other Vec<T>.
