Enum SemanticEvent

    Click {
        pos: Position,
        button: MouseButton,
    },
    DoubleClick {
        pos: Position,
        button: MouseButton,
    },
    TripleClick {
        pos: Position,
        button: MouseButton,
    },

        pos: Position,
        duration: Duration,
    },

        pos: Position,
        button: MouseButton,

        current: Position,
        delta: (i16, i16),
    },
    DragEnd {
        start: Position,
        end: Position,
    },
    DragCancel,
    Chord {
        sequence: Vec<ChordKey>,
    },
    Swipe {
        direction: SwipeDirection,
        distance: u16,
        velocity: f32,
    },
}

High-level semantic events derived from raw terminal input.

These represent user intentions rather than raw key presses or mouse coordinates. A gesture recognizer converts raw events into these.

Variants

Click

Single click (mouse down + up in same position within threshold).

Fields

pos: Position

button: MouseButton

DoubleClick

Two clicks within the double-click time threshold.

Fields

pos: Position

button: MouseButton

TripleClick

Three clicks within threshold (often used for line selection).

Fields

pos: Position

button: MouseButton

LongPress

Mouse held down beyond threshold without moving.

Fields

pos: Position

duration: Duration

DragStart

Mouse moved beyond drag threshold while button held.

Fields

pos: Position

button: MouseButton

DragMove

Ongoing drag movement.

Fields

start: Position

current: Position

delta: (i16, i16)

Movement since last DragMove (dx, dy).

DragEnd

Mouse released after drag.

Fields

start: Position

end: Position

DragCancel

Drag cancelled (Escape pressed, focus lost, etc.).

Chord

Key chord sequence completed (e.g., Ctrl+K, Ctrl+C).

Invariant: sequence is always non-empty.

Fields

sequence: Vec<ChordKey>

Swipe

Swipe gesture (rapid mouse movement in a cardinal direction).

Fields

direction: SwipeDirection

distance: u16

Distance in cells.

velocity: f32

Velocity in cells per second (always >= 0.0).

Implementations

impl SemanticEvent

pub fn is_drag(&self) -> bool

Returns true if this is a drag-related event.

pub fn is_click(&self) -> bool

Returns true if this is a click-related event (single, double, or triple).

pub fn position(&self) -> Option<Position>

Returns the position if this event has one.

pub fn button(&self) -> Option<MouseButton>

Returns the mouse button if this event involves one.

Trait Implementations

impl Clone for SemanticEvent

fn clone(&self) -> SemanticEvent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SemanticEvent

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

Formats the value using the given formatter.

impl PartialEq for SemanticEvent

fn eq(&self, other: &SemanticEvent) -> 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.
