Struct rama::tcp::client::service::Forwarder

pub struct Forwarder<C, L> { /* private fields */ }
Expand description

A TCP forwarder.

Implementations§

§

impl Forwarder<TcpConnector, ()>

pub fn new(target: impl Into<Authority>) -> Forwarder<TcpConnector, ()>

Create a new static forwarder for the given target Authority

pub fn ctx() -> Forwarder<TcpConnector, ()>

Create a new dynamic forwarder, which will fetch the target from the Context

§

impl<L> Forwarder<TcpConnector, L>

pub fn connector<T>(self, connector: T) -> Forwarder<T, L>

Set a custom “connector” for this forwarder, overwriting the default tcp forwarder which simply establishes a TCP connection.

This can be useful for any custom middleware, but also to enrich with rama-provided services for tls connections, HAproxy client endoding or even an entirely custom tcp connector service.

§

impl<C> Forwarder<C, ()>

pub fn layer<L>(self, layer_stack: L) -> Forwarder<C, L>

Define an Layer (stack) to create a Service stack through which the established connection will have to pass before actually forwarding.
