Struct TextPipeline 

pub struct TextPipeline {
    pipeline: RenderPipeline,
    bgl: BindGroupLayout,
    vertex_buffer: Buffer,
    vertex_capacity: u64,
    atlas: TextAtlas,
}

Text GPU pipeline. One render pipeline + a growable vertex buffer.

Fields

pipeline: RenderPipeline

bgl: BindGroupLayout

vertex_buffer: Buffer

vertex_capacity: u64

atlas: TextAtlas

Implementations

impl TextPipeline

pub fn new(device: &Device, queue: &Queue, format: TextureFormat) -> Self

pub fn atlas(&self) -> &TextAtlas

Borrow the atlas. Test surface.

pub fn record( &mut self, encoder: &mut CommandEncoder, queue: &Queue, device: &Device, target: &TextureView, frames: &[TextFrame], render_w: u32, render_h: u32, )

Render every queued text frame into target. No-op when the frame list is empty.

fn append_text( &mut self, verts: &mut Vec<TextQuadVertex>, frame: &TextFrame, render_w: u32, render_h: u32, )

Layout one text frame and append its glyph quads to verts. Lines are split on \n; horizontal anchor centres each line on frame.x, vertical anchor centres the whole block on frame.y.
