Struct BuiltinMarker 

pub struct BuiltinMarker {
    pub name: &'static str,
    pub kind: MarkerKind,
    pub applicable_to: ItemKinds,
}

Definition of a built-in marker.

Fields

name: &'static str

Marker name as it appears inside @mark(...) (e.g. “copy”).

kind: MarkerKind

What the marker does — a posture today, possibly more later.

applicable_to: ItemKinds

Item kinds the marker is applicable to.
