Module ref_or_owned 

Contains abstractions over references and ownership. Provides types which may represent either a borrowed reference or an owned value.

Both sized and unsized types may be used. References may be either mutable or immutable. The right enum should be chosen on these bases.

Enums

RefMutOrBox

A type which can be either a mutable reference, or an owned boxed value. Box is used for the owned variant because this type is primarily intended for use with unsized types, most particularly trait objects. For sized types, it is strongly suggested to use RefMutOrOwned instead.

RefMutOrOwned

A type which can be either a mutable reference, or an owned value. RefMutOrOwned requires sized types. For unsized types, use RefMutOrBox instead.

RefOrBox
