struct Deprecated

pub struct Deprecated :: [OnModule, OnTopLevel, OnMember]

Conforms to OnModule, OnTopLevel, OnMember.

Marks a declaration as deprecated.

Every use outside a deprecated declaration warns (LYR-SEM0076) with message. until names the release that removes it: a build with that toolchain version or later fails at the attribute (LYR-SEM0081). replacement is what the use should become, for the tools. It stands on a module, on what stands at a module's top level (an extend block for its members) and on a member; not on a parameter.
