Struct ClearPunch 

pub struct ClearPunch {
    pub strip_range: Range<usize>,
    pub bounds: RectU16,
    pub depth: u32,
}

One hoisted clear, ready to be issued as destination-out coverage.

Fields

strip_range: Range<usize>

Half-open range selecting this punch’s coverage from the frame’s shared strip storage.

The strips are generated after the frame’s draws and referenced by no draw, so a renderer that drops the punch pass reads the frame exactly as if the clear had never been recorded.

bounds: RectU16

The device-space rectangle the punch covers, clamped to the grid the strip pipeline addresses.

The coverage in strip_range is authoritative for which pixels are erased; this is the pass’s own extent, for a scissor or a bounds check.

depth: u32

The painter-order depth the punch was hoisted from.

A depth of its own rather than the depth of a neighbouring draw, so every draw recorded after the clear sits strictly in front of it. It is read twice: the renderer cuts the surface round at it (contract point 1) and the depth test uses it against the frame’s one depth-writing pass (contract point 3).
