    Begin,
    Commit,
    Rollback,
    Savepoint,
    ReleaseSavepoint,
    RollbackToSavepoint,
    Statement,
}

Used to detect when transactions begin and end for mode-aware pooling.

Variants

Begin

BEGIN or START TRANSACTION

Commit

COMMIT or END

Rollback

ROLLBACK

Savepoint

SAVEPOINT created

ReleaseSavepoint

RELEASE SAVEPOINT

RollbackToSavepoint

ROLLBACK TO SAVEPOINT

Statement

Regular statement (not transaction control)

Implementations

impl TransactionEvent

pub fn detect(sql: &str) -> Self

Parse SQL to detect transaction boundary

Arguments

• sql - SQL statement to parse

Returns

The detected transaction event type

pub fn is_transaction_end(&self) -> bool

Returns true if this event ends a transaction

pub fn is_transaction_start(&self) -> bool

Returns true if this event starts a transaction

Trait Implementations

impl Clone for TransactionEvent

fn clone(&self) -> TransactionEvent

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TransactionEvent

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for TransactionEvent

fn eq(&self, other: &TransactionEvent) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
