pub enum DatabaseErrorKind {
Deadlock,
SerializationFailure,
LockTimeout,
UniqueConstraint,
ForeignKeyConstraint,
}Expand description
Database failure classes that are stable enough for infrastructure retry decisions.
Variants§
Deadlock
The database aborted the current transaction because of a deadlock.
SerializationFailure
The database aborted the transaction because its serialization snapshot could not commit.
LockTimeout
The database rejected an operation after a lock wait timeout, or reported the database as busy/locked (SQLite).
UniqueConstraint
A unique or primary-key constraint rejected the operation.
ForeignKeyConstraint
A foreign-key constraint rejected the operation.
Implementations§
Source§impl DatabaseErrorKind
impl DatabaseErrorKind
Sourcepub fn is_transient_locking(self) -> bool
pub fn is_transient_locking(self) -> bool
Returns whether the failure class is a transient locking conflict that a bounded retry at the correct boundary can resolve.
