Enum AssocItemKind 

pub enum AssocItemKind {
    Const(Box<ConstItem>),
    Fn(Box<Fn>),
    Type(Box<TyAlias>),
    MacCall(Box<MacCall>),
    Delegation(Box<Delegation>),
    DelegationMac(Box<DelegationMac>),
}

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(Box<MacCall>)

A macro expanding to associated items.

Delegation(Box<Delegation>)

An associated delegation item.

DelegationMac(Box<DelegationMac>)

An associated list or glob delegation item.

Layout

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.
