Struct GlyphBatcher 

pub struct GlyphBatcher { /* private fields */ }

Builds and sorts batches from a flat list of glyphs each frame.

Usage:

batcher.begin();
for glyph in glyphs { batcher.push(glyph, key, instance); }
batcher.finish();
for batch in batcher.batches() { gpu.draw(batch); }

Implementations

impl GlyphBatcher

pub fn new() -> Self

pub fn begin(&mut self)

Clear pending list and stats. Call at the start of each frame.

pub fn push(&mut self, key: BatchKey, instance: GlyphInstance, depth: f32)

Submit a glyph for batching.

pub fn push_default( &mut self, layer: RenderLayer, instance: GlyphInstance, depth: f32, )

Submit a glyph using default batch key for its layer.

pub fn finish(&mut self)

Sort and group all pending glyphs into batches. Call after all pushes.

pub fn batches(&self) -> &[GlyphBatch]

Iterate over completed batches in draw order.

pub fn stats(&self) -> &BatchStats

Statistics from the last finish() call.

pub fn instance_count(&self) -> usize
