Struct CustomWaveRenderer 

pub struct CustomWaveRenderer {
    pipelines: [RenderPipeline; 4],
    vertex_buffer: Buffer,
    vertex_count: u32,
    batches: Vec<CustomWaveBatch>,
}

Custom-wave GPU pass. Owns one growable vertex buffer + two pipelines (lines and dots topology, alpha and additive blend = 4 combinations, indexed by pipeline_index(dots, additive)).

Fields

pipelines: [RenderPipeline; 4]

vertex_buffer: Buffer

vertex_count: u32

Logical vertex count after the most recent upload (0 when no custom waves are enabled).

batches: Vec<CustomWaveBatch>

Per-wave dispatch metadata, in stream order.

Implementations

impl CustomWaveRenderer

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

pub fn update( &mut self, queue: &Queue, vertices: &[CustomWaveVertex], batches: &[CustomWaveBatch], )

Replace the per-frame vertex stream and batch list. The combined vertex count is clamped to MAX_CUSTOM_WAVE_VERTICES; any tail past that is dropped (with a log::warn so it’s visible in long-running sessions).

pub fn render(&self, encoder: &mut CommandEncoder, view: &TextureView)

Issue one draw call per stored batch into view. Loads existing contents (no clear) — meant to draw on top of the warp + legacy waveform output.

pub fn vertex_count(&self) -> u32

Number of vertices held by the most recent Self::update call. Exposed for tests asserting the upload size.

pub fn batch_count(&self) -> usize

Number of dispatch batches the next Self::render will issue.
