pub enum NonMacroAttrKind {
Builtin(Symbol),
Tool,
DeriveHelper,
DeriveHelperCompat,
}
Expand description
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).
