Enum taffy::style::dimension::LengthPercentageAuto

pub enum LengthPercentageAuto {
    Length(f32),
    Percent(f32),
    Auto,
}

A unit of linear measurement

This is commonly combined with Rect, Point and Size<T>.

Variants

Length(f32)

An absolute length in some abstract units. Users of Taffy may define what they correspond to in their application (pixels, logical pixels, mm, etc) as they see fit.

Percent(f32)

The dimension is stored in percentage relative to the parent item.

Auto

The dimension should be automatically computed

Implementations

impl LengthPercentageAuto

pub fn resolve_to_option(self, context: f32) -> Option<f32>

Returns:

• Some(length) for Length variants
• Some(resolved) using the provided context for Percent variants
• None for Auto variants

pub fn is_auto(self) -> bool

Returns true if value is LengthPercentageAuto::Auto

Trait Implementations

impl Clone for LengthPercentageAuto

fn clone(&self) -> LengthPercentageAuto

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LengthPercentageAuto

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for LengthPercentageAuto

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<LengthPercentage> for LengthPercentageAuto

fn from(input: LengthPercentage) -> Self

Converts to this type from the input type.

impl From<LengthPercentageAuto> for Dimension

fn from(input: LengthPercentageAuto) -> Self

Converts to this type from the input type.

impl FromLength for LengthPercentageAuto

fn from_length<Input: Into<f32> + Copy>(value: Input) -> Self

Converts into an Into<f32> into Self

impl FromPercent for LengthPercentageAuto

fn from_percent<Input: Into<f32> + Copy>(percent: Input) -> Self

Converts into an Into<f32> into Self

impl MaybeResolve<Option<f32>, Option<f32>> for LengthPercentageAuto

fn maybe_resolve(self, context: Option<f32>) -> Option<f32>

Converts the given LengthPercentageAuto into an absolute length Can return None

impl PartialEq for LengthPercentageAuto

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