Expand description

An item declaration within the definition of a trait.

This type is available only if Syn is built with the "full" feature.

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.

`Method(TraitItemMethod)`

A trait method 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.
