Struct TileDescriptor 

pub struct TileDescriptor {
    prims: Vec<PrimitiveDescriptor>,
    pub local_valid_rect: PictureRect,
    last_updated_frame_id: FrameId,
    dep_data: Vec<u8>,
}

Uniquely describes the content of this tile, in a way that can be (reasonably) efficiently hashed and compared.

Fields

prims: Vec<PrimitiveDescriptor>

List of primitive instance unique identifiers. The uid is guaranteed to uniquely describe the content of the primitive template, while the other parameters describe the clip chain and instance params.

local_valid_rect: PictureRect

Picture space rect that contains valid pixels region of this tile.

last_updated_frame_id: FrameId

The last frame this tile had its dependencies updated (dependency updating is skipped if a tile is off-screen).

dep_data: Vec<u8>

Packed per-prim dependency information
