Enum RetainedKind 

pub enum RetainedKind {
    Record {
        rect: RectU16,
        retainable: bool,
    },
    Draw {
        depth: u32,
        window: RectU16,
        masked: bool,
    },
}

The two retained commands, as the store needs to see them.

Variants

Record

A PushRetained body: rendered into a page when the store admits it.

Fields

rect: RectU16

The bracket’s rect on the device grid, rounded out to whole tiles and clamped to the viewport — the most a page of this body may hold. A body whose own drawn bounds leave it painted outside its rectangle, which a page holding rect cannot carry anywhere else.

retainable: bool

Whether the body can be retained at all: it lay wholly inside the viewport and every scissor around it under no coverage mask (so nothing of it was clipped away on the way in), it drew no hole punch and no externally bound texture (whose pixels change with no command changing), and its bracket closed where it was opened.

Draw

A DrawRetained: a composite of a resident page.

Fields

depth: u32

The painter-order index the composite takes — the slot the command was recorded at.

window: RectU16

The device rectangle the composite may write: the viewport intersected with every scissor open around the command.

masked: bool

Whether a coverage-mask clip is open around the command, which a 1:1 composite cannot honour.
