Enum TraitItem

#[non_exhaustive]
pub enum TraitItem {
    Const(TraitItemConst),
    Fn(TraitItemFn),
    Type(TraitItemType),
    Macro(TraitItemMacro),
    Verbatim(TokenStream),
}

An item declaration within the definition of a trait.

Syntax tree enum

This type is a syntax tree enum.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Const(TraitItemConst)

An associated constant within the definition of a trait.

Fn(TraitItemFn)

An associated function within the definition of a trait.

Type(TraitItemType)

An associated type within the definition of a trait.

Macro(TraitItemMacro)

A macro invocation within the definition of a trait.

Verbatim(TokenStream)

Tokens within the definition of a trait not interpreted by Syn.

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.
