Enum rustc_hir::def::NonMacroAttrKind

pub enum NonMacroAttrKind {
    Builtin(Symbol),
    Tool,
    DeriveHelper,
    DeriveHelperCompat,
    Registered,
}

An attribute that is not a macro; e.g., #[inline] or #[rustfmt::skip].

Variants

Builtin(Symbol)

Single-segment attribute defined by the language (#[inline])

Tool

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

DeriveHelper

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

DeriveHelperCompat

Single-segment custom attribute registered by a derive macro but used before that derive macro was expanded (deprecated).

Registered

Single-segment custom attribute registered with #[register_attr].

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.
