Implementations

impl LanguageExtension

const READONLY_AND_READWRITE_STORAGE_TEXTURES: &'static str = "readonly_and_readwrite_storage_textures"

const PACKED4X8_INTEGER_DOT_PRODUCT: &'static str = "packed_4x8_integer_dot_product"

const POINTER_COMPOSITE_ACCESS: &'static str = "pointer_composite_access"

pub fn from_ident(s: &str) -> Option<Self>

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

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

Trait Implementations

impl Clone for LanguageExtension

fn clone(&self) -> LanguageExtension

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LanguageExtension

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

Formats the value using the given formatter.

impl Hash for LanguageExtension

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 LanguageExtension

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