`Const(ImplItemConst)`

An associated constant within an impl block.

`Method(ImplItemMethod)`

A method within an impl block.

`Type(ImplItemType)`

An associated type within an impl block.

`Macro(ImplItemMacro)`

A macro invocation within an impl block.

`Verbatim(TokenStream)`

Tokens within an impl block not interpreted by Syn.
