Struct Constructor 

pub struct Constructor {
    pub union: QualName,
    pub name: Name,
    pub index: usize,
    pub arity: usize,
}

A constructor, and its place in the declaration that declares it.

Both targets need all four: the name is the $ field’s value and the WIT case name, the index is the case’s position in the variant, the arity says how many arguments a saturated application supplies, and the union is which declaration the case belongs to.

Fields

union: QualName

The union this constructor builds, named by the package and module that declared it.

name: Name

The constructor’s own name, unqualified.

index: usize

Its position in that union’s declaration, counted from zero.

arity: usize

How many arguments it takes.
