pub enum Variant {
Ctor(Ident),
Identity,
}Expand description
One variant of a constructor — a selector-dispatched alternative for the
expanded parameter. A constructor with a single Ctor variant (and no
Identity) is the degenerate “single” form: applied unconditionally with no
selector. Two or more variants (or an Identity arm) get a runtime selector.
Variants§
Ctor(Ident)
Build the target by calling this constructor function.
Identity
Pass an already-built target value straight through.
