Struct RenderDataResources 

pub struct RenderDataResources { /* private fields */ }

The resource table of a render data stream: operations refer to resources by handle.

Implementations

impl RenderDataResources

pub fn count(&self) -> usize

pub fn intern(&mut self, resource: Option<RenderDataResource>) -> i32

Recording path: dedupes by reference equality so a resource reused across many draws gets one slot.

pub fn append_deserialized(&mut self, resource: RenderDataResource) -> i32

Deserialize path: appends without deduping since the wire format is already deduped.

pub fn get(&self, handle: i32) -> Option<&RenderDataResource>

The resource of a handle; None for NULL_HANDLE.

pub fn iter(&self) -> impl Iterator<Item = &RenderDataResource>

pub fn brush(&self, handle: i32) -> Option<&dyn IBrush>

pub fn pen(&self, handle: i32) -> Option<&dyn IPen>

pub fn geometry_impl(&self, handle: i32) -> Option<Arc<dyn IGeometryImpl>>

pub fn glyph_run(&self, handle: i32) -> Option<&Arc<dyn IGlyphRunImpl>>

pub fn bitmap(&self, handle: i32) -> Option<Arc<SharedBitmapImpl>>

pub fn custom_draw_operation( &self, handle: i32, ) -> Option<&Arc<dyn ICustomDrawOperation>>

pub fn effect(&self, handle: i32) -> Option<&Arc<dyn IImmutableEffect>>

pub fn dispose(&mut self)

Releases the table.

Trait Implementations

impl Default for RenderDataResources

fn default() -> Self
