Enum InstanceHead 

pub enum InstanceHead {
    Type(QualName, Vec<Name>),
    Tuple(Tuple<Name>),
    Unit,
}

The type an instance is for: a declared type applied to distinct variables, one per parameter; a tuple of distinct variables; or ().

Variants

Type(QualName, Vec<Name>)

A declared type, named by its declaration, and the variables it is applied to.

Tuple(Tuple<Name>)

Unit
