Enum taffy::style::LengthPercentageAuto

source ·
pub enum LengthPercentageAuto {
    Length(f32),
    Percent(f32),
    Auto,
}
Expand description

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§

source§

impl LengthPercentageAuto

source

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
source

pub fn is_auto(self) -> bool

Returns true if value is LengthPercentageAuto::Auto
