Enum LoadOp

pub enum LoadOp<V> {
    Clear(V),
    Load,
}

Operation to perform to the output attachment at the start of a render pass.

Corresponds to WebGPU GPULoadOp, plus the corresponding clearValue.

Variants

Clear(V)

Loads the specified value for this attachment into the render pass.

On some GPU hardware (primarily mobile), “clear” is significantly cheaper because it avoids loading data from main memory into tile-local memory.

On other GPU hardware, there isn’t a significant difference.

As a result, it is recommended to use “clear” rather than “load” in cases where the initial value doesn’t matter (e.g. the render target will be cleared using a skybox).

Load

Loads the existing value for this attachment into the render pass.

Trait Implementations

impl<V: Clone> Clone for LoadOp<V>

fn clone(&self) -> LoadOp<V>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<V: Debug> Debug for LoadOp<V>

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

Formats the value using the given formatter.

impl<V: Default> Default for LoadOp<V>

fn default() -> Self

Returns the “default value” for a type.

impl<'de, V> Deserialize<'de> for LoadOp<V>

where V: Deserialize<'de>,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<V: Hash> Hash for LoadOp<V>

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<V: PartialEq> PartialEq for LoadOp<V>

fn eq(&self, other: &LoadOp<V>) -> 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.

impl<V> Serialize for LoadOp<V>

where V: Serialize,

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<V: Copy> Copy for LoadOp<V>

impl<V: Eq> Eq for LoadOp<V>

impl<V> StructuralPartialEq for LoadOp<V>
