Scrolling types.

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.

None

No scrolling.

Jump

Jump to new location.

StepBackward

Step backward.

StepForward

Step forward.

PageBackward

Page backward.

PageForward

Page forward.

StepUp

Step up.

StepDown

Step down.

PageUp

Page up.

PageDown

Page down.

StepLeft

Step to the left.

StepRight

Step to the right.

PageLeft

Page to the left.

PageRight

Page to the right.

Start

Scroll to start.

End

Scroll to end.

Trait Implementations

impl Clone for ScrollType

fn clone(&self) -> ScrollType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ScrollType

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

Formats the value using the given formatter.

impl From<ScrollType> for Value

fn from(v: ScrollType) -> Self

Converts to this type from the input type.

impl<'a> FromValue<'a> for ScrollType

type Checker = GenericValueTypeChecker<ScrollType>

Value type checker.

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

Get the contained value from a Value.

impl HasParamSpec for ScrollType

type ParamSpec = ParamSpecEnum

type SetValue = ScrollType

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(_: &str, _: ScrollType) -> ParamSpecEnumBuilder<'_, ScrollType>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for ScrollType

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 ScrollType

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

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

fn partial_cmp(&self, other: &ScrollType) -> 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 StaticType for ScrollType

fn static_type() -> Type

Returns the type identifier of Self.

impl ToValue for ScrollType

fn to_value(&self) -> Value

Convert a value to a Value.

fn value_type(&self) -> Type

Returns the type identifier of self.

impl ValueType for ScrollType

type Type = ScrollType

Type to get the Type from.

impl Copy for ScrollType

impl Eq for ScrollType

impl StructuralPartialEq for ScrollType
