Type Definition melib::backends::notmuch::bindings::notmuch_database_begin_atomic

type notmuch_database_begin_atomic = unsafe extern "C" fn(notmuch: *mut notmuch_database_t) -> notmuch_status_t;

Begin an atomic database operation.

Any modifications performed between a successful begin and a notmuch_database_end_atomic will be applied to the database atomically. Note that, unlike a typical database transaction, this only ensures atomicity, not durability; neither begin nor end necessarily flush modifications to disk.

Atomic sections may be nested. begin_atomic and end_atomic must always be called in pairs.

Return value:

NOTMUCH_STATUS_SUCCESS: Successfully entered atomic section.

NOTMUCH_STATUS_XAPIAN_EXCEPTION: A Xapian exception occurred; atomic section not entered.
