Enum ShaderStage 

pub enum ShaderStage {
    Vertex,
    Fragment,
    Compute,
}

The shader stages a bind group layout entry is visible to.

The wire field is a bitmask, so entries are usually visible to more than one stage; the renderer ORs the selected variants together at the call site. This replaces the raw visibility: u32 on BindGroupLayoutEntry, where 0x1 / 0x2 / 0x4 were written by hand and a wrong bit silently produced a binding the shader cannot see.

Variants

Vertex

The vertex stage, mask value 0x1.

Fragment

The fragment stage, mask value 0x2.

Compute

The compute stage, mask value 0x4.

Implementations

impl ShaderStage

The GPUShaderStage bit one pipeline stage occupies.

pub fn stage_bit(self) -> u32

The GPUShaderStage bit this pipeline stage occupies.

Returns

• u32 - The bit this stage occupies in a BindGroupLayoutEntry visibility; combine several with |.

Trait Implementations

impl BitOr for ShaderStage

Combines two shader stages into the visibility bitmask a bind group layout entry expects.

The third of the three bitmask-carrying WebGPU enums; see BufferUsage for why combining is expressed as an operator rather than a helper call.

type Output = ShaderStages

The combined visibility bitmask.

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

Combines two shader stages into their visibility bitmask.

Arguments

• Self - The right-hand stage.

Returns

• Self::Output - The mask naming both stages.

impl BitOr<ShaderStage> for ShaderStages

Adding a stage to a mask that already names others.

type Output = ShaderStages

The widened mask.

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

Sets one more stage’s bit, leaving the existing bits alone.

Arguments

• ShaderStage - The stage to add.

Returns

• Self::Output - The mask naming both sides.

impl Clone for ShaderStage

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ShaderStage

impl Debug for ShaderStage

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

Formats the value using the given formatter.

impl Eq for ShaderStage

impl From<ShaderStage> for ShaderStages

Lets a lone stage stand in where a mask is expected, so every single-stage call site keeps reading as one.

fn from(value: ShaderStage) -> Self

Widens one stage into a mask naming only that stage.

Arguments

• ShaderStage - The stage the mask should name.

Returns

• ShaderStages - A mask with that stage’s single bit set.

impl Hash for ShaderStage

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 ShaderStage

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

Equality operator ==.

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

Inequality operator !=.
