Enum IndexTypeRef 

pub enum IndexTypeRef {
    Declared(TypeNameRef<Index>),
    NatRange(NatRangeIndexRef),
}

Type-level reference to an index definition.

Declared indexes are owner-qualified names. Compiler-generated range(N) axes are typed Nat-range identities and do not have declared resolved names.

Variants

Declared(TypeNameRef<Index>)

NatRange(NatRangeIndexRef)

Implementations

impl IndexTypeRef

pub fn from_resolved(resolved: ResolvedName<Index>) -> Self

Create a module-aware reference from a canonical resolved declared-index name.

pub fn with_owner(owner: DagId, name: NameDef<Index>) -> Self

Resolve a declared-index definition-site leaf into the given owner.

pub const fn with_display_leaf( name: NameDef<Index>, resolved: ResolvedName<Index>, ) -> Self

Create a reference with a display leaf that differs from the canonical owner-qualified identity.

pub const fn from_nat_range(index: NatRangeIndex) -> Self

Create a concrete compiler-generated Nat range reference.

pub fn from_nat_range_form( form: NatPolyForm, ) -> Result<Self, NatRangeIndexError>

Create a Nat range reference from a normalized Nat form.

Errors

Returns an error when the form is a concrete invalid Nat range size.

pub const fn from_nat_range_ref(reference: NatRangeIndexRef) -> Self

Wrap an already validated Nat range reference.

pub const fn declared_name(&self) -> Option<&NameDef<Index>>

The declared leaf name, when this is a declared index.

pub const fn declared_resolved(&self) -> Option<&ResolvedName<Index>>

The canonical declared owner/name identity, when this is a declared index.

pub const fn nat_range_ref(&self) -> Option<&NatRangeIndexRef>

Return the Nat range reference, when this is a compiler-generated Nat range.

pub const fn nat_range(&self) -> Option<NatRangeIndex>

Return the typed concrete Nat range identity, if this reference has one.

pub fn nat_range_form(&self) -> Option<NatPolyForm>

Return the normalized Nat form, when this is a Nat range reference.

pub fn display_name(&self) -> NameDef<Index>

Render a display-only leaf name for diagnostics and formatting.

pub fn matches_ref(&self, other: &Self) -> bool

Compare this reference against another type reference.

pub fn to_unowned_name(&self) -> NameDef<Index>

Clone the leaf definition/display name for diagnostic/display boundaries.

Trait Implementations

impl Clone for IndexTypeRef

fn clone(&self) -> IndexTypeRef

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for IndexTypeRef

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for IndexTypeRef

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for IndexTypeRef

impl From<ResolvedName<Index>> for IndexTypeRef

fn from(resolved: ResolvedName<Index>) -> Self

Converts to this type from the input type.

impl Hash for IndexTypeRef

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for IndexTypeRef

fn eq(&self, other: &IndexTypeRef) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
