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)

fn from(e: TraitItemMacro) -> TraitItem

Converts to this type from the input type.

impl From<TraitItemMethod> for TraitItem

fn from(e: TraitItemMethod) -> TraitItem

Converts to this type from the input type.

impl From<TraitItemType> for TraitItem
