Struct SDL_FingerID 

#[repr(transparent)]
pub struct SDL_FingerID(pub Uint64);

A unique ID for a single finger on a touch device.

This ID is valid for the time the finger (stylus, etc) is touching and will be unique for all fingers currently in contact, so this ID tracks the lifetime of a single continuous touch. This value may represent an index, a pointer, or some other unique ID, depending on the platform.

The value 0 is an invalid ID.

Availability

This datatype is available since SDL 3.2.0.

impl Hash for SDL_FingerID

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 SDL_FingerID

fn cmp(&self, other: &SDL_FingerID) -> 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<SDL_FingerID> for Uint64

fn eq(&self, other: &SDL_FingerID) -> 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 PartialEq<u64> for SDL_FingerID

fn eq(&self, other: &Uint64) -> 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 PartialEq for SDL_FingerID

fn eq(&self, other: &SDL_FingerID) -> 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 SDL_FingerID

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