Struct PaneId 

pub struct PaneId(pub u32);

Process-monotonic pane id. Distinct from BufferId: a pane holds a buffer + viewport, but two panes can show the same buffer. Allocated by PaneId::next at split time.

Tuple Fields

0: u32

Implementations

impl PaneId

pub const POPUP: Self

Reserved synthetic id for the floating-popup “pane”. The floating help popup is an overlay, not a pane-tree leaf, so the cells worker has no leaf to key its DisplayMatrix on. build_cells_panes registers the popup buffer under this sentinel id so BOTH popup states route through the shared compose_pane_lines reading a real matrix (Fork 1, popup unification). next() allocates from 1 upward and never reaches u32::MAX, so the sentinel can never collide with a real leaf.

Slice: PU.1b-3.

pub const COMPLETION_DOCS: Self

Reserved synthetic id for the Insert-mode completion-docs side popup — a SECOND simultaneous overlay (it coexists with the candidate list and, if open, the floating Self::POPUP). Like POPUP it is not a pane-tree leaf, so build_cells_panes registers its ephemeral backing buffer under this sentinel so the docs content routes through the same compose_pane_lines seam. u32::MAX - 1 — still far above any next()-allocated leaf.

Slice: PU.5.

pub const MINIBUFFER_BAND: Self

Reserved synthetic id for the minibuffer BAND — the advisory surface below all panes (which-key’s grid). A THIRD simultaneous overlay: it coexists with Self::POPUP by design, which is the whole point of the band. A popup and a band are different mechanisms — the popup slot is exclusive and the user asked for what is in it, while the band is advisory and timer-driven — so sharing one slot meant the band evicted whatever the user had open. u32::MAX - 2, still far above any next()-allocated leaf.

Slice: WK.12.

pub fn next() -> Self

Mint a fresh id from a process-wide counter starting at 1, so PaneId::default() (0) never names a real pane. Thread-safe.
