Enum Discriminator 

pub enum Discriminator {
    Arity(usize),
}

Discriminator that distinguishes overloads sharing one QName.

Currently only Arity is used (by ProcedureSurface to disambiguate arity overloads); the variant is kept open so future versioned families (e.g. type-set overloads) can extend it without breaking call sites.

Variants

Arity(usize)

Positional-argument arity.

Trait Implementations

impl Clone for Discriminator

fn clone(&self) -> Discriminator

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Discriminator

impl Debug for Discriminator

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

Formats the value using the given formatter.

impl Eq for Discriminator

impl Hash for Discriminator

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 Discriminator

fn eq(&self, other: &Discriminator) -> 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.
