Implementations

impl MetalBuiltin

pub fn attribute(&self) -> &'static str

The MSL attribute string for this built-in.

pub fn metal_type(&self) -> MetalType

Canonical MSL type for this built-in.

Trait Implementations

impl Clone for MetalBuiltin

fn clone(&self) -> MetalBuiltin

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MetalBuiltin

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

Formats the value using the given formatter.

impl Hash for MetalBuiltin

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 MetalBuiltin

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