Function wgpu_core::track::texture::insert_or_barrier_update

unsafe fn insert_or_barrier_update(
    texture_selector: &TextureSelector,
    start_state: Option<&mut TextureStateSet>,
    current_state_set: &mut TextureStateSet,
    resource_metadata: &mut ResourceMetadata<Arc<Texture>>,
    index: usize,
    start_state_provider: TextureStateProvider<'_>,
    end_state_provider: Option<TextureStateProvider<'_>>,
    metadata_provider: ResourceMetadataProvider<'_, Arc<Texture>>,
    barriers: &mut Vec<PendingTransition<TextureUses>>,
)

If the resource isn’t tracked

• Inserts the given resource.
• Uses the start_state_provider to populate start_states
• Uses either end_state_provider or start_state_provider to populate current_states.

If the resource is tracked

• Inserts barriers from the state in current_states to the state provided by start_state_provider.
• Updates the current_states with either the state from end_state_provider or start_state_provider.

Any barriers are added to the barrier vector.

Safety

Indexes must be valid indexes into all arrays passed in to this function, either directly or via metadata or provider structs.
