Struct PlatformScrollConfig 

pub struct PlatformScrollConfig {
    pub wheel_line_step: Dp,
}

Platform-specific wheel scroll normalization parameters.

Fields

wheel_line_step: Dp

Density-independent distance consumed for one wheel line step.

Implementations

impl PlatformScrollConfig

pub fn current() -> Self

Returns the default configuration for the current compilation target.

pub fn normalize_scroll_delta( self, delta_x: f32, delta_y: f32, unit: ScrollDeltaUnit, source: ScrollEventSource, ) -> (f32, f32)

Converts a raw platform scroll delta into logical scroll pixels.

Trait Implementations

impl Clone for PlatformScrollConfig

fn clone(&self) -> PlatformScrollConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PlatformScrollConfig

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

Formats the value using the given formatter.

impl Default for PlatformScrollConfig

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for PlatformScrollConfig

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