Implementations

impl EnableExtension

const F16: &'static str = "f16"

const CLIP_DISTANCES: &'static str = "clip_distances"

const DUAL_SOURCE_BLENDING: &'static str = "dual_source_blending"

pub(crate) fn from_ident(word: &str, span: Span) -> Result<Self, Error<'_>>

Convert from a sentinel word in WGSL into its associated EnableExtension, if possible.

pub const fn to_ident(self) -> &'static str

Maps this EnableExtension into the sentinel word associated with it in WGSL.

Trait Implementations

impl Clone for EnableExtension

fn clone(&self) -> EnableExtension

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for EnableExtension

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

Formats the value using the given formatter.

impl Hash for EnableExtension

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 EnableExtension

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