Struct ResolvedDeclaration 

pub struct ResolvedDeclaration {
    pub selector: Arc<ComplexSelector>,
    pub name: String,
    pub value: CssValue,
    pub specificity: (u32, u32, u32),
    pub order: usize,
    pub important: bool,
    pub origin: StyleOrigin,
    pub media_queries: Arc<Vec<AtQuery>>,
}

A single CSS declaration after selector resolution and value processing.

ResolvedDeclaration represents one property-value pair that has been fully associated with a selector and enriched with all information required for CSS cascade resolution.

This structure is produced after:

• Parsing selectors
• Resolving var() using custom properties
• Computing selector specificity

During the cascade phase, multiple ResolvedDeclarations with the same property name may compete. The winner is determined by comparing:

1. important declarations
2. cascade origin
3. specificity (higher specificity wins)
4. order (later declarations win)

Fields

selector: Arc<ComplexSelector>

name: String

value: CssValue

specificity: (u32, u32, u32)

order: usize

important: bool

origin: StyleOrigin

media_queries: Arc<Vec<AtQuery>>

Nested @media/@supports conditions which must all match before this declaration applies. Shared across declarations of the same rule block.

Implementations

impl ResolvedDeclaration

pub fn outranks(&self, other: &Self) -> bool

pub fn matches_media(&self, environment: &MediaEnvironment) -> bool

Returns whether every enclosing @media rule matches environment.
