StyledNode

Struct StyledNode 

Source
pub struct StyledNode<'a> {
    pub node: &'a Node,
    pub specified_values: BTreeMap<String, String>,
    pub hover_values: Option<BTreeMap<String, String>>,
    pub focus_values: Option<BTreeMap<String, String>>,
    pub active_values: Option<BTreeMap<String, String>>,
    pub css_vars: Rc<BTreeMap<String, String>>,
    pub children: Vec<StyledNode<'a>>,
}

Fields§

§node: &'a Node§specified_values: BTreeMap<String, String>§hover_values: Option<BTreeMap<String, String>>§focus_values: Option<BTreeMap<String, String>>

:focus 適用時に差分が生じる算出値(hover_values と同じ方式)。 事前に通常値と focus 時の値を両方計算しておき、実際にどちらを使うかは 描画側が focused_id と element_id の一致を見て選ぶ。フォーカス変更自体は DOM を変更しないため dom_needs_rebuild では再レイアウトが保証されず、 この事前計算方式(hover と同様)が必要。

§active_values: Option<BTreeMap<String, String>>

:active 適用時に差分が生じる算出値(hover_values/focus_values と同じ事前計算方式)。 実際の適用可否は描画側が「要素がホバー中 かつ マウス左ボタン押下中」を見て選ぶ。

§css_vars: Rc<BTreeMap<String, String>>

この要素のスコープで有効な CSS 変数(--foo)。

親から受け継いだ内容をそのまま持つノードが大半なので Rc で共有し、 変数を定義するノードだけが実体を複製する(cascade.rs 参照)。

§children: Vec<StyledNode<'a>>
