Struct DisplayList 

pub struct DisplayList { /* private fields */ }

DisplayList is an immutable recording of drawing commands.

Display lists are GPU-free, thread-safe, and nestable. Wrap a list in Arc to share or replay it without copying its commands.

Implementations

impl DisplayList

pub fn id(&self) -> u64

id returns the process-unique identity of this live display list.

Deserialization creates a fresh identity; equal content does not imply equal identity.

pub fn ops(&self) -> &[Op]

ops returns the recorded commands in replay order.

pub fn bounds(&self) -> Option<Rect>

bounds returns the union of visible draw bounds in list coordinates.

It returns None when the list draws nothing.

pub fn draw_count(&self) -> u32

draw_count returns the number of draws, including nested lists.

pub fn depth_slots(&self) -> u32

depth_slots returns the ordering slots required to replay this list.

pub fn backdrop_reads(&self) -> u32

backdrop_reads counts backdrop reads when replayed, shared or not, nested lists included.

pub fn backdrop_group(&self, key: u64) -> Option<&BackdropGroup>

backdrop_group returns the group recorded for key, if present.
