Struct PointerInfo 

pub struct PointerInfo {
    pub pointer_id: Option<PointerId>,
    pub persistent_device_id: Option<PersistentDeviceId>,
    pub pointer_type: PointerType,
}

Identifying information about a pointer, stable across states.

Fields

pointer_id: Option<PointerId>

Pointer ID.

PointerId::PRIMARY is reserved for the primary pointer, so when converting platform pointer IDs on a platform that does not reserve this value, add an offset to avoid collision.

None is for events not originating from a pointing device.

persistent_device_id: Option<PersistentDeviceId>

Persistent device ID.

This should be set when the platform can identify a given pointing device during the whole session, and associate it with events. If this is not possible for the given event, it should be None.

pointer_type: PointerType

Pointer type.

Implementations

impl PointerInfo

pub fn is_primary_pointer(&self) -> bool

Returns true if this is the primary pointer.

Trait Implementations

impl Clone for PointerInfo

fn clone(&self) -> PointerInfo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PointerInfo

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

Formats the value using the given formatter.

impl Hash for PointerInfo

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for PointerInfo

fn cmp(&self, other: &PointerInfo) -> 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.

impl PartialEq for PointerInfo

fn eq(&self, other: &PointerInfo) -> 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 PartialOrd for PointerInfo

fn partial_cmp(&self, other: &PointerInfo) -> 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

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