Function mariadb_sys::handler_column_bitmaps_signal

pub unsafe extern "C" fn handler_column_bitmaps_signal(
    this: *mut c_void
)

Signal that the table->read_set and table->write_set table maps changed The handler is allowed to set additional bits in the above map in this call. Normally the handler should ignore all calls until we have done a ha_rnd_init() or ha_index_init(), write_row(), update_row or delete_row() as there may be several calls to this routine.
