Struct UiLayerRenderer

Source

pub struct UiLayerRenderer { /* private fields */ }

Expand description

Renderer for the screen-space UI layer.

Holds CPU-side instance buffers and converts UiDrawCommands into GlyphInstances positioned in screen-pixel coordinates.

Implementations§

Source §

impl UiLayerRenderer

Source

pub fn new() -> Self

Source

pub fn begin(&mut self)

Clear instance buffers. Call at the start of each frame.

Source

pub fn build_instances(&mut self, ui: &UiLayer, atlas: &FontAtlas)

Process all draw commands from the UI layer and build instance buffers.

Source

pub fn glyph_instances(&self) -> &[GlyphInstance]

Get the glyph instances for GPU upload.

Source

pub fn glyph_bytes(&self) -> &[u8] ⓘ

Get glyph instance data as raw bytes for GPU upload.

Source

pub fn rect_instances(&self) -> &[RectInstance]

Get rect instances for GPU upload.

Source

pub fn rect_bytes(&self) -> &[u8] ⓘ

Get rect instance data as raw bytes.

Source

pub fn glyph_count(&self) -> usize

Total glyph count.

Source

pub fn rect_count(&self) -> usize

Total rect count.

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

Source §

impl<T> Downcast for T
where T: Any,

Source §

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

Source §

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.

Source §

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

Source §

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.

Source §

impl<T> DowncastSync for T
where T: Any + Send + Sync,

Source §

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Sync + Send>

Convert Arc<Trait> (where Trait: Downcast) to Arc<Any>. Arc<Any> can then be further downcast into Arc<ConcreteType> where ConcreteType implements Trait.
