Enum rustc_ap_rustc_ast::ast::AssocItemKind

pub enum AssocItemKind {
    Const(Defaultness, P<Ty>, Option<P<Expr>>),
    Fn(Box<FnKind>),
    TyAlias(Box<TyAliasKind>),
    MacCall(MacCall),
}

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(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<FnKind>)

An associated function.

TyAlias(Box<TyAliasKind>)

An associated type.

MacCall(MacCall)

A macro expanding to associated items.
