Enum cairo_lang_semantic::items::generics::GenericArgumentHead

pub enum GenericArgumentHead {
    Type(TypeHead),
    Impl(ImplHead),
    Const,
}

Head of a generic argument. A non-param non-variable generic argument has a head, which represents the kind of the root node in its tree. This is used for caching queries for fast lookups when the generic argument is not completely inferred yet.

Trait Implementations

impl Clone for GenericArgumentHead

fn clone(&self) -> GenericArgumentHead

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for GenericArgumentHead

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

Formats the value using the given formatter.

impl Hash for GenericArgumentHead

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 GenericArgumentHead

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

This method tests for self and other values to be equal, and is used by ==.

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

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