Map a backend feature from subcontext B to context A.

This is useful when you have a context composed of multiple subcontexts. It prevents you to manually map the feature.

See a usage example at ../../tests/dynamic_backend.rs.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
