Enum gtk::ScrollablePolicy

#[non_exhaustive]
pub enum ScrollablePolicy {
    Minimum,
    Natural,
    // some variants omitted
}

Defines the policy to be used in a scrollable widget when updating the scrolled window adjustments in a given orientation.

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.

Minimum

Scrollable adjustments are based on the minimum size

Natural

Scrollable adjustments are based on the natural size

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ScrollablePolicy

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

Formats the value using the given formatter.

impl Display for ScrollablePolicy

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

impl<'a> FromValue<'a> for ScrollablePolicy

type Checker = GenericValueTypeChecker<ScrollablePolicy>

Value type checker.

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

Get the contained value from a Value.

impl Hash for ScrollablePolicy

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,

Feeds a slice of this type into the given Hasher.

impl Ord for ScrollablePolicy

fn cmp(&self, other: &ScrollablePolicy) -> Ordering

This method returns an Ordering between self and other.

const fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

const fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

const fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<ScrollablePolicy> for ScrollablePolicy

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd<ScrollablePolicy> for ScrollablePolicy

fn partial_cmp(&self, other: &ScrollablePolicy) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

fn static_type() -> Type

Returns the type identifier of Self.

impl ToValue for ScrollablePolicy

fn to_value(&self) -> Value
