Struct InputMetrics 

#[repr(C)]
pub struct InputMetrics {
    pub double_click_time_ms: u32,
    pub double_click_distance_px: f32,
    pub drag_threshold_px: f32,
    pub caret_blink_rate_ms: u32,
    pub caret_width_px: f32,
    pub wheel_scroll_lines: u32,
    pub hover_time_ms: u32,
}

Input interaction timing and distance thresholds from the OS.

These values are queried from the operating system to match the user’s configured double-click speed, drag sensitivity, caret blink rate, etc.

Platform APIs

• macOS: NSEvent.doubleClickInterval
• Windows: GetDoubleClickTime(), GetSystemMetrics(SM_CXDOUBLECLK), GetCaretBlinkTime(), SystemParametersInfo(SPI_GETWHEELSCROLLLINES)
• Linux: XDG Desktop Portal / gsettings

Fields

double_click_time_ms: u32

Max milliseconds between clicks to register a double-click.

double_click_distance_px: f32

Max pixels the mouse can move between clicks and still count.

drag_threshold_px: f32

Pixels the mouse must move while held down before a drag starts.

caret_blink_rate_ms: u32

Caret blink rate in milliseconds (0 = no blink).

caret_width_px: f32

Width of the text caret/cursor in pixels (typically 1–2).

wheel_scroll_lines: u32

Lines to scroll per mouse wheel notch.

hover_time_ms: u32

Milliseconds to wait before a hover triggers (e.g. tooltip delay). Windows: SystemParametersInfo(SPI_GETMOUSEHOVERTIME) — default 400.

Trait Implementations

impl Clone for InputMetrics

fn clone(&self) -> InputMetrics

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InputMetrics

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

Formats the value using the given formatter.

impl Default for InputMetrics

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for InputMetrics

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

impl Copy for InputMetrics

impl StructuralPartialEq for InputMetrics
