Expand description

Represents associated item kinds.

The term “provided” in the variants below refers to the item having a default definition / body. Meanwhile, a “required” item lacks a definition / body. In an implementation, all items must be provided. The Options below denote the bodies, where Some(_) means “provided” and conversely None means “required”.

Variants§

§

Const(Box<ConstItem>)

An associated constant, const $ident: $ty $def?; where def ::= "=" $expr? ;. If def is parsed, then the constant is provided, and otherwise required.

§

Fn(Box<Fn>)

An associated function.

§

Type(Box<TyAlias>)

An associated type.

§

MacCall(P<MacCall>)

A macro expanding to associated items.

§

Delegation(Box<Delegation>)

An associated delegation item.

§

DelegationMac(Box<DelegationMac>)

An associated delegation item list.
