Enum ScrollSource

#[non_exhaustive]
pub enum ScrollSource {
    Unknown,
    Wheel,
    Finger,
    Continuous,
}

The scroll source determines the source of the scroll event. Keep in mind that the source device InputDeviceType is not enough to infer the scroll source.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Unknown

Source of scroll events is unknown.

Wheel

The scroll event is originated by a mouse wheel.

Finger

The scroll event is originated by one or more fingers on the device (eg. touchpads).

Continuous

The scroll event is originated by the motion of some device (eg. a scroll button is set).

Trait Implementations

impl Clone for ScrollSource

fn clone(&self) -> ScrollSource

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ScrollSource

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

Formats the value using the given formatter.

impl Display for ScrollSource

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

Formats the value using the given formatter.

impl<'a> FromValue<'a> for ScrollSource

unsafe fn from_value(value: &Value) -> Self

Safety

impl<'a> FromValueOptional<'a> for ScrollSource

unsafe fn from_value_optional(value: &Value) -> Option<Self>

Safety

impl Hash for ScrollSource

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 ScrollSource

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

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

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

impl SetValue for ScrollSource

unsafe fn set_value(value: &mut Value, this: &Self)

Safety

impl StaticType for ScrollSource

fn static_type() -> Type

Returns the type identifier of Self.

impl Copy for ScrollSource

impl Eq for ScrollSource
