Struct PointerScaling 

pub struct PointerScaling(/* private fields */);

A pointer-motion multiplier in 8.8 fixed point (0x0100 is 1×).

Zero is excluded: it is not a meaningful multiplier, so a zero on the wire surfaces as Hidpp20Error::UnsupportedResponse.

Implementations

impl PointerScaling

pub const ONE: PointerScaling

Unscaled pointer motion (1×), the spec’s default.

pub const fn from_raw(raw: u16) -> Option<PointerScaling>

Wraps a raw 8.8 fixed-point value; None for zero.

pub const fn raw(self) -> u16

The raw 8.8 fixed-point value.

pub fn multiplier(self) -> f32

The multiplier as a float (1.0 for Self::ONE).

Trait Implementations

impl Ord for PointerScaling

fn cmp(&self, other: &PointerScaling) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for PointerScaling

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for PointerScaling

fn partial_cmp(&self, other: &PointerScaling) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.
