Enum ContentFit

#[non_exhaustive]
pub enum ContentFit {
    Fill,
    Contain,
    Cover,
    ScaleDown,
}

Available on crate feature v4_8 only.

Controls how a content should be made to fit inside an allocation.

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.

Fill

Make the content fill the entire allocation, without taking its aspect ratio in consideration. The resulting content will appear as stretched if its aspect ratio is different from the allocation aspect ratio.

Contain

Scale the content to fit the allocation, while taking its aspect ratio in consideration. The resulting content will appear as letterboxed if its aspect ratio is different from the allocation aspect ratio.

Cover

Cover the entire allocation, while taking the content aspect ratio in consideration. The resulting content will appear as clipped if its aspect ratio is different from the allocation aspect ratio.

ScaleDown

The content is scaled down to fit the allocation, if needed, otherwise its original size is used.

Trait Implementations

impl Clone for ContentFit

fn clone(&self) -> ContentFit

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ContentFit

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

Formats the value using the given formatter.

impl From<ContentFit> for Value

fn from(v: ContentFit) -> Self

Converts to this type from the input type.

impl<'a> FromValue<'a> for ContentFit

type Checker = GenericValueTypeChecker<ContentFit>

Value type checker.

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

Get the contained value from a Value.

impl HasParamSpec for ContentFit

type ParamSpec = ParamSpecEnum

type SetValue = ContentFit

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for ContentFit

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 ContentFit

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

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

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

fn static_type() -> Type

Returns the type identifier of Self.

impl ToValue for ContentFit

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 ContentFit

type Type = ContentFit

Type to get the Type from.

impl Copy for ContentFit

impl Eq for ContentFit

impl StructuralPartialEq for ContentFit
