Struct wgpu_core::track::texture::ComplexTextureState

struct ComplexTextureState {
    mips: ArrayVec<RangedStates<u32, TextureUses>, { _ }>,
}

Represents the complex state of textures where every subresource is potentially in a different state.

Fields

mips: ArrayVec<RangedStates<u32, TextureUses>, { _ }>

Implementations

impl ComplexTextureState

fn new(mip_level_count: u32, array_layer_count: u32) -> Self

Creates complex texture state for the given sizes.

This state will be initialized with the UNKNOWN state, a special state which means the trakcer knows nothing about the state.

unsafe fn from_selector_state_iter( full_range: TextureSelector, state_iter: impl Iterator<Item = (TextureSelector, TextureUses)>, ) -> Self

Initialize a complex state from a selector representing the full size of the texture and an iterator of a selector and a texture use, specifying a usage for a specific set of subresources.

Self::to_selector_state_iter can be used to create such an iterator.

Safety

All selectors in the iterator must be inside of the full_range selector.

The full range selector must have mips and layers start at 0.

fn to_selector_state_iter( &self, ) -> impl Iterator<Item = (TextureSelector, TextureUses)> + Clone + '_

Convert a complex state into an iterator over all states stored.

Self::from_selector_state_iter can be used to consume such an iterator.

Trait Implementations

impl Clone for ComplexTextureState

fn clone(&self) -> ComplexTextureState

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ComplexTextureState

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

Formats the value using the given formatter.

impl Default for ComplexTextureState

fn default() -> ComplexTextureState

Returns the “default value” for a type.

impl PartialEq for ComplexTextureState

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
