Struct StyleValues 

pub struct StyleValues {
    pub display: Option<Display>,
    pub position: Option<Position>,
    pub inset: Option<Edges>,
    pub width: Option<Length>,
    pub height: Option<Length>,
    pub min_height: Option<Length>,
    pub fill: Option<Option<Fill>>,
    pub shadows: Option<Vec<ShadowSpec>>,
    pub border: Option<Option<Border>>,
    pub opacity: Option<Option<f32>>,
    pub text_color: Option<Color>,
}

A value for some of the StyleFields; None leaves a field out.

Fields

display: Option<Display>

Style::display.

position: Option<Position>

Style::position.

inset: Option<Edges>

Style::inset.

width: Option<Length>

Style::width.

height: Option<Length>

Style::height.

min_height: Option<Length>

Style::min_height.

fill: Option<Option<Fill>>

Visuals::fill.

shadows: Option<Vec<ShadowSpec>>

Visuals::shadows.

border: Option<Option<Border>>

Visuals::border.

opacity: Option<Option<f32>>

The Opacity component; Some(None) is no component.

text_color: Option<Color>

TextStyle::color.

Implementations

impl StyleValues

pub fn fields(&self) -> StyleFields

The fields this sets.

pub fn read(fields: StyleFields, live: &Live<'_>) -> Self

Read fields off the live components. A field whose component is missing is left out, except opacity, whose absence is a value.

pub fn overlay(&mut self, top: &StyleValues)

Lay top over these values: every field it sets wins.

pub fn restricted(self, fields: StyleFields) -> Self

Keep only fields.

pub fn write_style(&self, style: &mut impl DerefMut<Target = Style>)

Write the layout fields this sets onto style, touching only the ones that differ so an unchanged value marks nothing changed.

pub fn write_visuals(&self, visuals: &mut impl DerefMut<Target = Visuals>)

Write the paint fields this sets onto visuals, touching only the ones that differ.

pub fn write_text(&self, text: &mut impl DerefMut<Target = TextStyle>)

Write the text color this sets onto text, if it differs.

pub fn opacity_change( &self, current: Option<&Opacity>, ) -> Option<Option<Opacity>>

What to do with the Opacity component to make it hold the opacity this sets: None leaves it as it is, Some(None) removes it, Some(Some(o)) writes o.

Trait Implementations

impl Clone for StyleValues

fn clone(&self) -> StyleValues

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StyleValues

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

Formats the value using the given formatter.

impl Default for StyleValues

fn default() -> StyleValues

Returns the “default value” for a type.

impl PartialEq for StyleValues

fn eq(&self, other: &StyleValues) -> 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.
