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 Option
s below denote the bodies, where Some(_)
means “provided” and conversely None
means “required”.
Variants§
Const(Defaultness, P<Ty>, Option<P<Expr>>)
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.

attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
