}

Variants

Builtin

Tool

Multi-segment custom attribute living in a "tool module" (#[rustfmt::skip]).

DeriveHelper

Single-segment custom attribute registered by a derive macro (#[serde(default)]).

Implementations

impl NonMacroAttrKind

pub fn descr(self) -> &'static str

pub fn article(self) -> &'static str

pub fn is_used(self) -> bool

Users of some attributes cannot mark them as used, so they are considered always used.
