Enum StyleDefinition 

pub enum StyleDefinition {
    Alias(String),
    Attributes {
        base: StyleAttributes,
        light: Option<StyleAttributes>,
        dark: Option<StyleAttributes>,
    },
}

Parsed style definition from YAML.

Represents a single style entry before building into console::Style.

Variants

Alias(String)

Alias to another style by name.

Alias chains are resolved during theme building.

Attributes

Concrete style definition with optional mode overrides.

• base: Attributes shared across all modes
• light: Optional overrides for light mode (merged onto base)
• dark: Optional overrides for dark mode (merged onto base)

Fields

base: StyleAttributes

Base style attributes (used when no mode override exists).

light: Option<StyleAttributes>

Light mode overrides (merged onto base).

dark: Option<StyleAttributes>

Dark mode overrides (merged onto base).

Implementations

impl StyleDefinition

pub fn parse(value: &Value, style_name: &str) -> Result<Self, StylesheetError>

Parses a style definition from a YAML value.

Determines the definition type based on the value structure:

• String → Alias or Shorthand (depends on content)
• Mapping → Full definition with optional light/dark

pub fn is_alias(&self) -> bool

Returns true if this is an alias definition.

pub fn alias_target(&self) -> Option<&str>

Returns the alias target if this is an alias, None otherwise.

Trait Implementations

impl Clone for StyleDefinition

fn clone(&self) -> StyleDefinition

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StyleDefinition

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

Formats the value using the given formatter.

impl PartialEq for StyleDefinition

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