ResolvedStyle

Struct ResolvedStyle 

Source
pub struct ResolvedStyle { /* private fields */ }
Expand description

Resolved style for one node — property -> value, with cascade already applied. Adapter crates (e.g. hjkl-css-floem) convert this to their own builder type.

Internally each property stores the (rule_idx, decl_idx) of the winning declaration so that iter can replay properties in CSS source order, which is the correct semantic for adapters that apply shorthand/longhand overrides.

Implementations§

Source§

impl ResolvedStyle

Source

pub fn get(&self, property: &str) -> Option<&Value>

Source

pub fn len(&self) -> usize

Source

pub fn is_empty(&self) -> bool

Source

pub fn iter(&self) -> impl Iterator<Item = (&str, &Value)>

Iterate declarations in CSS source order: ascending rule_idx of the winning declaration, with decl_idx (position inside the rule) breaking ties. The result matches the order in which the declarations appeared in the stylesheet so that adapters applying properties sequentially produce CSS-spec behaviour for shorthand/longhand collisions.

Example: x { border-color: blue; border: 1px solid red; } yields ("border-color", blue) then ("border", red). An adapter that applies border-color first then border ends up with red, which is the CSS-correct winner.

If you need alphabetical order for snapshots or serialization, collect the iterator and sort the resulting Vec by key.

Performance: allocates a Vec and sorts it on every call. For one-shot adapter conversion this cost is negligible.
