Enum CutServiceability 

pub enum CutServiceability {
    Servable,
    Unservable {
        reason: UnservableReason,
        at: usize,
    },
}

Whether an overlay can draw a cut’s range exactly as the main surface would — cut_is_servable’s answer.

Variants

Servable

The overlay draws the range; the main segment excludes it.

Unservable

The range stays on the main surface and the overlay draws nothing.

Fields

reason: UnservableReason

Why.

at: usize

The command index that decided it: the offending command, or the PushRetained opening the crossing bracket.

Implementations

impl CutServiceability

pub fn is_servable(self) -> bool

Whether the overlay serves the cut.

pub fn served_range(self, cut: &Range<usize>) -> Range<usize>

The range the overlay records for cut, and the main segment excludes: cut itself when servable, otherwise the empty range 0..0 — nothing reopened, nothing drawn, the overlay cleared to transparent.
