Struct FrameInput 

pub struct FrameInput {
    pub keys_pressed: HashSet<KeyCode>,
    pub keys_held: HashSet<KeyCode>,
    pub modifiers: Modifiers,
    pub drag_started: HashSet<MouseButton>,
    pub dragging: HashSet<MouseButton>,
    pub drag_delta: Vec2,
    pub scroll_delta: f32,
    pub clicked: HashSet<MouseButton>,
    pub pointer_delta: Vec2,
    pub hovered: bool,
    pub ctrl_scroll_orbit_delta: Vec2,
    pub shift_scroll_pan_delta: Vec2,
}

Per-frame input snapshot populated by the egui adapter.

This is framework-agnostic - the egui-specific translation happens in the host application’s viewport adapter.

Fields

keys_pressed: HashSet<KeyCode>

Keys pressed this frame (rising edge).

keys_held: HashSet<KeyCode>

Keys held this frame.

modifiers: Modifiers

Current modifier state.

drag_started: HashSet<MouseButton>

Mouse buttons that started a drag this frame.

dragging: HashSet<MouseButton>

Mouse buttons currently being dragged.

drag_delta: Vec2

Accumulated drag delta this frame (pixels).

scroll_delta: f32

Scroll delta this frame (positive = up/zoom-in).

clicked: HashSet<MouseButton>

Mouse buttons clicked this frame (press + release without drag).

pointer_delta: Vec2

Raw pointer movement delta this frame (pixels), regardless of button state. Used for manipulation modes where mouse movement alone drives transforms.

hovered: bool

Whether the input area (viewport) is hovered.

ctrl_scroll_orbit_delta: Vec2

Ctrl+scroll orbit delta in logical pixels (x = yaw, y = pitch). Read from raw MouseWheel events to preserve 2D direction — smooth_scroll_delta loses directional data when modifiers are held.

shift_scroll_pan_delta: Vec2

Shift+scroll pan delta in logical pixels (x = right, y = up). Read from raw MouseWheel events for the same reason as ctrl_scroll_orbit_delta.

Trait Implementations

impl Clone for FrameInput

fn clone(&self) -> FrameInput

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FrameInput

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

Formats the value using the given formatter.

impl Default for FrameInput

fn default() -> Self

Returns the “default value” for a type.
