Struct BuiltinTypeConstructor 

pub struct BuiltinTypeConstructor {
    pub name: &'static str,
    pub arity: usize,
    pub kind: BuiltinTypeConstructorKind,
}

Definition of a built-in parameterized type constructor.

Built-in type constructors share a single surface form with user-defined comptime-generic functions that return type (e.g. fn Vec(comptime T: type) -> type): both are written Name(arg1, arg2, ...) in type position. The difference is that built-in constructors are hard-wired in the compiler — sema resolves the name against this registry and lowers directly to a TypeKind without running the comptime interpreter.

See ADR-0061 (Ptr/MutPtr) and ADR-0062 (Ref/MutRef) for usage.

Fields

name: &'static str

Constructor name as it appears in source code (e.g., “Ptr”).

arity: usize

kind: BuiltinTypeConstructorKind

Which built-in lowering to use.
