Struct yrs::YMapEvent

#[repr(C)]
pub struct YMapEvent {
    pub txn: *const Transaction,
    /* private fields */
}

Event pushed into callbacks registered with ymap_observe function. It contains all key-value changes made within a scope of corresponding transaction (see: ymap_event_keys) as well as navigation data used to identify a YMap instance which triggered this event.

Fields

txn: *const Transaction
