Struct medea_reactive::MutObservableFieldGuard

pub struct MutObservableFieldGuard<'a, D, S>where
    S: OnObservableFieldModification<D>,
    D: PartialEq,{ /* private fields */ }

Mutable ObservableField reference returned by ObservableField::borrow_mut.

When this guard is Dropped, a check for modifications will be performed. If data was changed, then OnObservableFieldModification::on_modify will be called.
