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(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 list or glob delegation item.

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...)
attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
