Enum LengthAuto 

pub enum LengthAuto {
    Px(f32),
    Percent(f32),
    Auto,
    Vw(f32),
    Vh(f32),
    Vmin(f32),
    Vmax(f32),
}

Length value that can also be Auto (for margins/insets).

Similar to Length but allows automatic positioning.

Variants

Px(f32)

Fixed pixel value

Percent(f32)

Percentage of parent size (0.0 - 100.0)

Auto

Automatic positioning

Vw(f32)

Percentage of viewport width (0.0 - 100.0)

Vh(f32)

Percentage of viewport height (0.0 - 100.0)

Vmin(f32)

Percentage of smaller viewport dimension (0.0 - 100.0)

Vmax(f32)

Percentage of larger viewport dimension (0.0 - 100.0)

Implementations

impl LengthAuto

pub fn px(value: f32) -> Self

Create a pixel length.

pub fn percent(value: f32) -> Self

Create a percentage length.

pub fn auto() -> Self

Create an auto length.

pub fn vw(value: f32) -> Self

Create a viewport width length (1vw = 1% of viewport width).

pub fn vh(value: f32) -> Self

Create a viewport height length (1vh = 1% of viewport height).

pub fn vmin(value: f32) -> Self

Create a viewport minimum length (1vmin = 1% of smaller viewport dimension).

pub fn vmax(value: f32) -> Self

Create a viewport maximum length (1vmax = 1% of larger viewport dimension).

pub fn resolve(self, viewport_size: Vec2) -> Self

Resolve viewport-relative units to pixels.

pub fn to_length_percentage_auto(self) -> LengthPercentageAuto

Convert to Taffy LengthPercentageAuto.

Panics

Panics if called on viewport-relative units (Vw/Vh/Vmin/Vmax). These must be resolved to pixels first using LengthAuto::resolve.

pub fn from_length_percentage_auto(lpa: LengthPercentageAuto) -> Self

Convert from Taffy LengthPercentageAuto.

Trait Implementations

impl Clone for LengthAuto

fn clone(&self) -> LengthAuto

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LengthAuto

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

Formats the value using the given formatter.

impl Display for LengthAuto

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

Formats the value using the given formatter.

impl From<Length> for LengthAuto

fn from(length: Length) -> Self

Converts to this type from the input type.

impl From<LengthAuto> for Constraint

fn from(length: LengthAuto) -> Self

Converts to this type from the input type.

impl From<LengthAuto> for LengthPercentageAuto

fn from(length: LengthAuto) -> Self

Converts to this type from the input type.

impl From<f32> for LengthAuto

fn from(value: f32) -> Self

Converts to this type from the input type.

impl PartialEq for LengthAuto

fn eq(&self, other: &LengthAuto) -> 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 Copy for LengthAuto
