Enum Value 

pub enum Value {
    Color(Color),
    Length(Length),
    LengthSet(Vec<Length>),
    Keyword(String),
    Auto,
    Number(f64),
    FontFamilyList(Vec<String>),
    Border {
        width: Length,
        color: Color,
    },
    SideSet(Vec<SideValue>),
}

Variants

Color(Color)

Length(Length)

LengthSet(Vec<Length>)

1..=4 lengths, as in CSS shorthand: padding: 1px / padding: 1px 2px / padding: 1px 2px 3px / padding: 1px 2px 3px 4px.

Keyword(String)

Auto

auto keyword used with sizing and margin properties.

Number(f64)

Unitless number — flex-grow, flex-shrink, line-height, font-weight (numeric form).

FontFamilyList(Vec<String>)

font-family list: one or more family names in source order. Quoted strings and bare idents both land here as plain strings.

Border

border / border-{side} / outline shorthand. style is dropped — floem has no border-style model; border: 1px none #fff treats none as zero width (same as omitting a visible line). The solid token, if present, is accepted and ignored.

Fields

width: Length

color: Color

SideSet(Vec<SideValue>)

1..=4 side values where each side may be a length or auto. Used for margin / padding shorthands that contain auto.

Trade-off: a separate SideSet variant rather than making Length an Option<Length> or adding Length::Auto. Keeping Length as a pure numeric type avoids propagating auto-awareness into every length consumer; adapters that only care about LengthSet stay unchanged.

Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Value

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

Formats the value using the given formatter.

impl PartialEq for Value

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