Enum wgpu_core::track::texture::TextureStateProvider

enum TextureStateProvider<'a> {
    KnownSingle {
        state: TextureUses,
    },
    Selector {
        selector: TextureSelector,
        state: TextureUses,
    },
    TextureSet {
        set: &'a TextureStateSet,
    },
}

A source of texture state.

Variants

KnownSingle

Comes directly from a single state.

Fields

state: TextureUses

Selector

Comes from a selector and a single state.

Fields

selector: TextureSelector

state: TextureUses

TextureSet

Comes from another texture set.

Fields

set: &'a TextureStateSet

Implementations

impl<'a> TextureStateProvider<'a>

fn from_option(selector: Option<TextureSelector>, state: TextureUses) -> Self

Convenience function turning Option<Selector> into this enum.

unsafe fn get_state( self, texture_selector: Option<&TextureSelector>, index: usize, ) -> SingleOrManyStates<TextureUses, impl Iterator<Item = (TextureSelector, TextureUses)> + Clone + 'a>

Get the state provided by this.

Panics

Panics if texture_selector is None and this uses a Selector source.

Safety

• The index must be in bounds of the state set if this uses an TextureSet source.

Trait Implementations

impl<'a> Clone for TextureStateProvider<'a>

fn clone(&self) -> TextureStateProvider<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.
