Crate optionable_derive 

This crate is on its own not really usable. It is re-exported together with the required traits in the optionable crate. The relevant docs can be also found there.

This is only a separate crate as derive macros have to be a separate crate.

Derive Macros

Optionable

Derive macro to derive the Optionable trait for structs/enums recursively by generating a type with all fields recursively replaced with Option versions. All non-required fields have to implement the Optionable trait. This trait is already implemented by this library for many primitive types, wrapper and container types.
