Struct ConnectionBuilder

pub struct ConnectionBuilder { /* private fields */ }

Build connection to Tarantool.

Implementations

impl ConnectionBuilder

pub async fn build<A>(&self, addr: A) -> Result<Connection, Error>

where A: ToSocketAddrs + Display + Clone + Send + Sync + 'static,

Create connection to Tarantool using provided address.

pub fn auth<'a>( &mut self, user: &str, password: impl Into<Option<&'a str>>, ) -> &mut Self

Sets user login and, optionally, password, used for this connection.

AUTH message sent upon connecting to server.

pub fn timeout(&mut self, timeout: impl Into<Option<Duration>>) -> &mut Self

Sets timeout for requests.

By default disabled.

pub fn transaction_timeout( &mut self, transaction_timeout: impl Into<Option<Duration>>, ) -> &mut Self

Sets default timeout for transactions.

By default disabled.

pub fn transaction_isolation_level( &mut self, transaction_isolation_level: TransactionIsolationLevel, ) -> &mut Self

Sets default transaction isolation level.

By default TransactionIsolationLevel::Default (i.e. use box.cfg default value).

pub fn connect_timeout( &mut self, connect_timeout: impl Into<Option<Duration>>, ) -> &mut Self

Sets timeout for connect.

By default disabled.

pub fn reconnect_interval( &mut self, reconnect_interval: impl Into<Option<ReconnectInterval>>, ) -> &mut Self

Sets interval between reconnection attempts.

If disabled, next attempt wil lbe started as soon as last one finished.

By default set to ReconnectInterval::exponential_backoff(Duration::from_millis(1), Duration::from_secs(1), 0.5, 5.0).

pub fn sql_statement_cache_capacity(&mut self, capacity: usize) -> &mut Self

Sets capacity of SQL statment cache.

Setting 0 disables cache. By default set to 100.

pub fn internal_simultaneous_requests_threshold( &mut self, value: usize, ) -> &mut Self

Prepare Connection to process value number of simultaneously created requests.

It is not hard limit, but making more simultaneous requests than this value will result in degradation in performance, so try to increase this value, if you unsatisfied with performance.

Internally connection have multiple bounded channels, and this parameter mostly affect size of this channels. Increasing this value can help if you have a lot of simultaneously created requests, however this will increase memory consumption.

By default set to 500, which should be reasonable compromise between memory (about 100 KB) and performance.
