Enum cairo_lang_semantic::items::imp::ImplHead

source · 
pub enum ImplHead {
    Concrete(ImplDefId),
}
Expand description

Head of an impl. A non-param non-variable impl has a head, which represents the kind of the root node in its tree representation. This is used for caching queries for fast lookups when the impl is not completely inferred yet.
