Struct LayeredCss

pub struct LayeredCss {
    pub styles: BTreeMap<ScopeId, StyleTree>,
}

Fields

styles: BTreeMap<ScopeId, StyleTree>

We store each chains in a groups with root_scope_id as identifier of the group.

Implementations

impl LayeredCss

pub fn new() -> Self

pub fn root_scope_exist(&self, root_scope_id: impl Into<ScopeId>) -> bool

pub fn layer_exist_in_root_scope( &self, root_scope_id: impl Into<ScopeId>, layer_scope_id: impl Into<ScopeId>, ) -> bool

pub fn add_style_from_parts( &mut self, root_scope_id: impl Into<ScopeId>, order_in_chain: Order, layer_scope_id: impl Into<ScopeId>, style: impl Into<Style>, ) -> bool

Add new style layer to root_scope_id. Returns false if layer already exists.

pub fn add_style_with_order<T>( &mut self, root_scope_id: ScopeId, order_in_chain: Order, ) -> bool

where T: ScopeCommon,

Add new style layer. Uses ScopeCommon implementation to retrieve layer_scope_id and style. Returns false if layer already exists.

pub fn add_style_chain<C>(&mut self, ts_chain: &C) -> bool

where C: ScopeChainOps,

Add chain of styles to registry. Uses information from ScopeChain implementation, to retrieve scope_id of each layer and its style. Automatically detects root_scope_id and sets order based on distance from root. Ignore empty styles.

Return true if any of the layers is new.
