Struct ConnectionLease 

pub struct ConnectionLease { /* private fields */ }

A leased connection with mode-aware lifecycle management

Implementations

impl ConnectionLease

pub fn new( connection: PooledConnection, mode: PoolingMode, client_id: ClientId, ) -> Self

Create a new connection lease

pub fn connection(&self) -> &PooledConnection

Get the underlying connection (immutable)

pub fn connection_mut(&mut self) -> &mut PooledConnection

Get the underlying connection (mutable)

pub fn into_connection(self) -> PooledConnection

Take ownership of the underlying connection

pub fn mode(&self) -> PoolingMode

Get the pooling mode

pub fn client_id(&self) -> ClientId

Get the client ID

pub fn in_transaction(&self) -> bool

Check if currently in a transaction

pub fn statements_executed(&self) -> u64

Get the number of statements executed

pub fn lease_duration(&self) -> Duration

Get how long this lease has been held

pub fn on_statement_complete(&mut self, sql: &str) -> LeaseAction

Process a statement and determine if connection should be released

Arguments

• sql - The SQL statement that was executed

Returns

The action to take with this connection

pub fn on_transaction_end(&mut self) -> LeaseAction

Called when transaction ends (from backend ReadyForQuery status)

This is a more reliable way to detect transaction end than parsing SQL.

pub fn update_transaction_state(&mut self, in_transaction: bool)

Update transaction state from backend ReadyForQuery status

Arguments

• in_transaction - Whether backend reports being in a transaction

pub fn should_release(&self) -> bool

Check if connection should be released based on current state
