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