Struct FingerId 

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

Identifier of a finger in a touch event.

Whenever a touch event is received it contains a FingerId which uniquely identifies the finger used for the current interaction.

Implementations

impl FingerId

pub const fn into_raw(self) -> usize

Convert the FingerId into the underlying integer.

This is useful if you need to pass the ID across an FFI boundary, or store it in an atomic.

pub const fn from_raw(id: usize) -> Self

Construct a FingerId from the underlying integer.

This should only be called with integers returned from FingerId::into_raw.

Trait Implementations

impl Clone for FingerId

fn clone(&self) -> Self

Returns a duplicate of the value.

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

impl Ord for FingerId

fn cmp(&self, other: &Self) -> 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,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

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 FingerId

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for FingerId

fn partial_cmp(&self, other: &Self) -> 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.

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