TcpConnector

rama::tcp::client::service

Struct TcpConnector 

pub struct TcpConnector<StreamConnector = ()> { /* private fields */ }
Available on crate features std and tcp only.
Expand description

A connector which can be used to establish a TCP connection to a server.

Implementations§

§

impl TcpConnector

pub fn new() -> TcpConnector

Create a new TcpConnector, which is used to establish a connection to a server.

You can use middleware around the TcpConnector or add connection pools, retry logic and more.

§

impl<StreamConnector> TcpConnector<StreamConnector>

pub fn with_max_in_flight_connect_attempts( self, n: usize, ) -> TcpConnector<StreamConnector>

Set the maximum number of resolved candidate connection attempts raced concurrently (default 3, clamped to a minimum of 1).

Only takes effect when a ConnectorTargetStream is present on the input (i.e. a domain target was resolved by an upstream DNS connector), a single IP target is dialed directly.

pub fn set_max_in_flight_connect_attempts( &mut self, n: usize, ) -> &mut TcpConnector<StreamConnector>

Set the maximum number of resolved candidate connection attempts raced concurrently (default 3, clamped to a minimum of 1).

Only takes effect when a ConnectorTargetStream is present on the input (i.e. a domain target was resolved by an upstream DNS connector), a single IP target is dialed directly.

§

impl TcpConnector

pub fn with_connector<StreamConnector>( self, connector: StreamConnector, ) -> TcpConnector<StreamConnector>

Consume self to attach the given Connector (a TcpStreamConnector), used to establish the actual TcpStream.
