Struct MutationObserverOptions 

pub struct MutationObserverOptions {
    pub child_list: bool,
    pub attributes: bool,
    pub character_data: bool,
    pub subtree: bool,
    pub attribute_old_value: bool,
    pub character_data_old_value: bool,
    pub attribute_filter: Option<Vec<String>>,
}

MutationObserver.observe() で指定される監視オプション

Fields

child_list: bool

attributes: bool

character_data: bool

subtree: bool

attribute_old_value: bool

character_data_old_value: bool

attribute_filter: Option<Vec<String>>

Implementations

impl MutationObserverOptions

pub fn new() -> Self

pub fn normalize( self, attributes_specified: bool, character_data_specified: bool, ) -> Result<Self, &'static str>

W3C 仕様準拠のオプション正規化・バリデーション:

• attributes が未指定でも attributeOldValue / attributeFilter があれば attributes = true
• characterData が未指定でも characterDataOldValue があれば characterData = true
• childList, attributes, characterData のいずれも true でなければエラー
• 矛盾したオプション組み合わせの検査

pub fn matches_attribute(&self, attr_name: &str) -> bool

属性名が監視条件に合致するか判定
