Locks

Struct Locks 

Source
pub struct Locks {
    pub locks: Vec<Lock>,
}
Expand description

Every FOR … locking clause on one statement.

A statement may carry several, one per table, so this is a list. It writes no keyword of its own — each Lock starts with FOR — so a query renders it as w.write_if(!locks.is_empty(), " ", &locks, "").

Fields§

§locks: Vec<Lock>

The locking clauses, in order.

Implementations§
