Struct webrender::render_task_graph::Surface

struct Surface {
    kind: RenderTargetKind,
    allocator: GuillotineAllocator,
    is_shared: bool,
    free_after: PassId,
}

An internal representation of a dynamic surface that tasks can be allocated into. Maintains some extra metadata about each surface during the graph build.

Fields

kind: RenderTargetKind

Whether this is a color or alpha render target

allocator: GuillotineAllocator

Allocator for this surface texture

is_shared: bool

We can only allocate into this for reuse if it’s a shared surface

free_after: PassId

The pass that we can free this surface after (guaranteed to be the same for all tasks assigned to this surface)

Implementations

impl Surface

fn alloc_rect( &mut self, size: DeviceIntSize, kind: RenderTargetKind, is_shared: bool, free_after: PassId, ) -> Option<DeviceIntPoint>

Allocate a rect within a shared surfce. Returns None if the format doesn’t match, or allocation fails.

Trait Implementations

impl Serialize for Surface

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
