Trait Maplike

    type Value: ToJSValConvertible;

    // Required methods
    fn get_index(&self, index: u32) -> Option<(Self::Key, Self::Value)>;
    fn get(&self, key: Self::Key) -> Option<Self::Value>;
    fn size(&self) -> u32;

Expand description

Every Maplike dom_struct must implement this to provide access to underlying storage so codegen can automatically generate all maplike methods

In case you use a type that implements Maplike as underlying storage it’s recommended to use maplike macro.
