Enum Token 

pub enum Token {
    Color(Color),
    Length(Length),
    BoxEdges(BoxEdges),
    BorderStyle(BorderStyle),
    Var {
        name: String,
    },
}

A CSS custom-property value. Supports Color, Length, BoxEdges (for padding/margin), and BorderStyle (for border-style). These are the value types whose fields carry var() references: the color fields (color, background, underline-color, border color), the length fields (width/height), padding/margin, and a border’s style. A border’s edges (Borders) cannot yet be driven by var().

Token::Var covers the case where a custom property is itself a bare var(--other) reference: its ultimate type (color vs length vs edges vs style) is not knowable at parse time, so it is stored untyped and resolved by following the chain via ThemeTokens::get_color / ThemeTokens::get_length / ThemeTokens::get_box_edges / ThemeTokens::get_border_style.

Variants

Color(Color)

Length(Length)

BoxEdges(BoxEdges)

BorderStyle(BorderStyle)

Var

A bare var(--other) reference whose type is determined by what --other ultimately resolves to. Every typed getter follows the chain.

Trait Implementations

impl Clone for Token

fn clone(&self) -> Token

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Token

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

Formats the value using the given formatter.

impl From<&str> for Token

Parse a CSS string into a Token. Mirrors [Color::from(&str)]: a valid color expression becomes Token::Color; anything else (including a valid length like "50%") degrades to a reset color. This keeps the ergonomic tokens_mut().insert("accent", "#00d4ff") form working for the common color case; for a length token, pass a Length explicitly.

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<BorderStyle> for Token

fn from(b: BorderStyle) -> Self

Converts to this type from the input type.

impl From<BoxEdges> for Token

fn from(e: BoxEdges) -> Self

Converts to this type from the input type.

impl From<Color> for Token

fn from(c: Color) -> Self

Converts to this type from the input type.

impl From<Length> for Token

fn from(l: Length) -> Self

Converts to this type from the input type.

impl From<String> for Token

fn from(s: String) -> Self

Converts to this type from the input type.

impl PartialEq for Token

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