Struct wgpu_core::track::UsageScope

pub(crate) struct UsageScope<A: HalApi> {
    pub buffers: BufferUsageScope<A>,
    pub textures: TextureUsageScope<A>,
}

A usage scope tracker. Only needs to store stateful resources as stateless resources cannot possibly have a usage conflict.

Fields

buffers: BufferUsageScope<A>

textures: TextureUsageScope<A>

Implementations

impl<A: HalApi> UsageScope<A>

pub fn new( buffers: &Storage<Buffer<A>, BufferId>, textures: &Storage<Texture<A>, TextureId> ) -> Self

Create the render bundle scope and pull the maximum IDs from the hubs.

pub unsafe fn merge_bind_group( &mut self, textures: &Storage<Texture<A>, TextureId>, bind_group: &BindGroupStates<A> ) -> Result<(), UsageConflict>

Merge the inner contents of a bind group into the usage scope.

Only stateful things are merged in here, all other resources are owned indirectly by the bind group.

Safety

The maximum ID given by each bind group resource must be less than the length of the storage given at the call to new.

pub unsafe fn merge_render_bundle( &mut self, textures: &Storage<Texture<A>, TextureId>, render_bundle: &RenderBundleScope<A> ) -> Result<(), UsageConflict>

Merge the inner contents of a bind group into the usage scope.

Only stateful things are merged in here, all other resources are owned indirectly by a bind group or are merged directly into the command buffer tracker.

Safety

The maximum ID given by each bind group resource must be less than the length of the storage given at the call to new.

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

Formats the value using the given formatter.
