Struct AtlasPageBuffers 

pub struct AtlasPageBuffers {
    pub instances: Vec<GpuStrip>,
    pub alphas: Vec<u8>,
}

One page’s lowered replay: the instances to draw and the coverage they index.

Reused across pages and across frames rather than allocated per page — the two vectors are the only heap a replay costs once they have grown, which is the point of handing them to the lowering closure instead of taking a fresh pair back from it.

The two are kept together because a strip instance’s alpha column is only meaningful against the coverage buffer generated alongside it, the same pairing crate::compile::CompiledFrame keeps for a frame.

Fields

instances: Vec<GpuStrip>

The page’s strip instances, in the order they are drawn.

alphas: Vec<u8>

The coverage bytes instances index.

Implementations

impl AtlasPageBuffers

pub fn clear(&mut self)

Empties both buffers, keeping their capacity for the next page.

pub fn is_empty(&self) -> bool

Whether this page would draw nothing.
