Enum PaneCommand 

pub enum PaneCommand {
    FocusNext,
    FocusPrevious,
    FocusDirectional(PaneCardinalDirection),
    FocusEdge(PaneCardinalDirection),
    ResizeStep {
        direction: PaneResizeDirection,
        units: u16,
    },
    Split(SplitAxis),
    Close,
    MovePane(PaneCardinalDirection),
    SwapPane(PaneFocusOrdinal),
    Maximize,
    Restore,
}

The canonical, host-agnostic pane keyboard command vocabulary.

Hosts translate raw key events into these commands; resolve maps each to a deterministic outcome. Resize unit counts are supplied by the caller (computed via PaneCommandAcceleration) so the command itself stays a pure intent.

Variants

FocusNext

Move focus to the next leaf in deterministic focus order (cyclic).

FocusPrevious

Move focus to the previous leaf in deterministic focus order (cyclic).

FocusDirectional(PaneCardinalDirection)

Move focus to the nearest leaf in a direction (spatial).

FocusEdge(PaneCardinalDirection)

Move focus to the extreme leaf in a direction (jump to edge).

ResizeStep

Grow (Increase) or shrink (Decrease) the active pane by units snap steps, resizing its enclosing split.

Fields

direction: PaneResizeDirection

Increase grows the active pane; Decrease shrinks it.

units: u16

Number of snap steps (one step = PANE_SNAP_DEFAULT_STEP_BPS).

Split(SplitAxis)

Split the active leaf along axis, adding a new sibling leaf.

Close

Close the active leaf, promoting its sibling.

MovePane(PaneCardinalDirection)

Move the active pane to dock against the nearest pane in a direction.

SwapPane(PaneFocusOrdinal)

Swap the active pane with its cyclic neighbour.

Maximize

Maximize the active pane (transient view state; no topology change).

Restore

Restore from a maximized state (transient view state).

Trait Implementations

impl Clone for PaneCommand

fn clone(&self) -> PaneCommand

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for PaneCommand

impl Debug for PaneCommand

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for PaneCommand

impl PartialEq for PaneCommand

fn eq(&self, other: &PaneCommand) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
