Enum StyleValue 

pub enum StyleValue<T> {
    Animated(T),
    Val(T),
    Unset,
    Base,
}

The value for a [Style] property in the public API.

This represents the result of reading a style property, with additional states like Base that indicate inheritance from parent styles.

Variants

Animated(T)

Value inserted by animation interpolation

Val(T)

Value set directly

Unset

Use the default value for the style, typically from the underlying ComputedStyle.

Base

Use whatever the base style is. For an overriding style like hover, this uses the base style. For the base style, this is equivalent to Unset.

Implementations

impl<T> StyleValue<T>

pub fn map<U>(self, f: impl FnOnce(T) -> U) -> StyleValue<U>

pub fn unwrap_or(self, default: T) -> T

Trait Implementations

impl<T: Clone> Clone for StyleValue<T>

fn clone(&self) -> StyleValue<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for StyleValue<T>

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

Formats the value using the given formatter.

impl<T> Default for StyleValue<T>

fn default() -> StyleValue<T>

Returns the “default value” for a type.

impl<T> From<T> for StyleValue<T>

fn from(x: T) -> Self

Converts to this type from the input type.

impl<T: PartialEq> PartialEq for StyleValue<T>

fn eq(&self, other: &StyleValue<T>) -> 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.
