Struct ShaderFeatureFlags 

pub struct ShaderFeatureFlags(pub u32);

Shader feature flags that control permutation generation. Each enabled feature adds to the shader permutation count. Use specialization constants to reduce permutations.

Tuple Fields

0: u32

Implementations

pub fn count(self) -> u32

Returns the number of enabled features (permutation count contribution).

pub fn is_within_permutation_limit(self) -> bool

Returns the permutation index for this feature combination.

pub fn has(self, flag: Self) -> bool

Trait Implementations

impl BitAnd for ShaderFeatureFlags

type Output = ShaderFeatureFlags

The resulting type after applying the & operator.

fn bitand(self, rhs: Self) -> Self::Output

Performs the & operation.

impl BitOr for ShaderFeatureFlags

type Output = ShaderFeatureFlags

The resulting type after applying the | operator.

fn bitor(self, rhs: Self) -> Self::Output

Performs the | operation.

impl Clone for ShaderFeatureFlags

fn clone(&self) -> ShaderFeatureFlags

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ShaderFeatureFlags

impl Debug for ShaderFeatureFlags

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

Formats the value using the given formatter.

impl Default for ShaderFeatureFlags

fn default() -> ShaderFeatureFlags

Returns the “default value” for a type.

impl Eq for ShaderFeatureFlags

impl Hash for ShaderFeatureFlags

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 ShaderFeatureFlags

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