Enum Length 

pub enum Length {
    Fixed(f32),
    Fill,
    Shrink,
    FillPortion(u8),
    Percentage(f32),
}

Length specification for widget sizing

Variants

Fixed(f32)

Exact pixel value

Fill

Expand to fill available space

Shrink

Minimize to content size

FillPortion(u8)

Proportional fill (1-255)

Percentage(f32)

Percentage of parent (0.0-100.0)

Implementations

impl Length

pub fn parse(s: &str) -> Result<Self, String>

Parse from string representation

Examples

use dampen_core::ir::layout::Length;

assert_eq!(Length::parse("200"), Ok(Length::Fixed(200.0)));
assert_eq!(Length::parse("fill"), Ok(Length::Fill));
assert_eq!(Length::parse("shrink"), Ok(Length::Shrink));
assert_eq!(Length::parse("fill_portion(3)"), Ok(Length::FillPortion(3)));
assert_eq!(Length::parse("50%"), Ok(Length::Percentage(50.0)));

Trait Implementations

impl Clone for Length

fn clone(&self) -> Length

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Length

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Length

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Length

fn eq(&self, other: &Length) -> 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 Serialize for Length

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
