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])

Tuple Fields of Builtin

0: Symbol

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.

Trait Implementations

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
