impl Theme

pub fn validate(&self, _allow_partial: bool) -> Result<(), String>

Validate theme with detailed error messages

• Palette colors are invalid or missing
• Typography values are invalid
• Spacing unit is non-positive

For themes with inheritance, validates only set colors For themes without inheritance, validates all required colors

pub fn validate_inheritance( &self, all_themes: &HashMap<String, Theme>, visited: &mut Vec<String>, ) -> Result<(), ThemeError>

Validate theme inheritance

Returns an error if:

• Parent theme doesn’t exist
• Circular inheritance detected
• Inheritance depth exceeds 5 levels

pub fn inherit_from(&self, parent: &Theme) -> Self

Inherit properties from a parent theme

The child theme’s values take precedence, but missing values are inherited from the parent theme.

Trait Implementations

impl Clone for Theme

fn clone(&self) -> Theme

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Theme

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Theme

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Theme

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

where __S: Serializer,
