Expand description

An Ability classifies what operations are permitted for a given type

Variants

Copy

Allows values of types with this ability to be copied, via CopyLoc or ReadRef

Drop

Allows values of types with this ability to be dropped, via Pop, WriteRef, StLoc, Eq, Neq, or if left in a local when Ret is invoked Technically also needed for numeric operations (Add, BitAnd, Shift, etc), but all of the types that can be used with those operations have Drop

Store

Allows values of types with this ability to exist inside a struct in global storage

Key

Allows the type to serve as a key for global storage operations: MoveTo, MoveFrom, etc.
