Struct DisplayList 

pub struct DisplayList { /* private fields */ }

Recorded paint commands. Cloning is a reference-count bump; the command buffer is copied only when a shared list is mutated.

Implementations

impl DisplayList

pub const fn new() -> Self

pub fn push(&mut self, command: PaintCommand)

pub fn extend_from(&mut self, other: &Self)

pub fn detach_surface_partitions( &self, selected: &HashSet<SurfacePartitionId>, ) -> (Self, HashMap<SurfacePartitionId, Self>)

Splits selected retained surface partitions out of this display list.

Commands inside an active selected partition are omitted from parent and returned under that partition’s stable identity. Nested selected partitions are assigned to the deepest selected surface, so a submenu can be detached independently from its owning menu. Partition markers never reach either output.

pub fn translated(&self, offset: Offset) -> Self

Wraps this list in one logical translation without mutating retained command geometry.

pub fn begins_with_opaque_surface_rect(&self, surface_size: Size) -> bool

Conservatively proves that the first visual operation covers the entire target with an opaque axis-aligned rectangle.

This is intentionally stricter than a general coverage analysis. A backend may use it before presenting through an opaque native surface; returning false means “not proven” and must never be interpreted as transparency being unnecessary.

pub fn commands(&self) -> &[PaintCommand]

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn clear(&mut self)

Removes every command, keeping the allocation for the next recording.
