Enum Length 

pub enum Length {
    Px(f64),
    Percent(f64),
}

Length carries f64 payloads so it intentionally only implements PartialEq — f64 is not Eq. By extension, Value::LengthSet and any container of Value cannot be Eq either. Adapters that want hashable/Eq-equivalent comparison should compare a derived representation (e.g. rendered floem Style).

Variants

Px(f64)

CSS pixels. Unitless values in the source are parsed as Px too — floem doesn’t distinguish, and the layout engine treats both the same.

em / rem are deferred to a later phase; document the gap here so it is easy to find.

Percent(f64)

<n>% of the parent’s relevant dimension.

Implementations

impl Length

pub fn as_px(self) -> Option<f64>

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 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 Copy for Length

impl StructuralPartialEq for Length
