Expand description

the proxy handler


construct a new proxy handler that sends all requests to the url provided. if the url contains a path, the inbound request path will be joined onto the end.

use trillium_smol::{TcpConnector, ClientConfig};
use trillium_proxy::Proxy;

let proxy = Proxy::<TcpConnector>::new("");

chainable constructor to specify the client Connector configuration

use trillium_smol::{TcpConnector, ClientConfig};
use trillium_proxy::Proxy;
let proxy = Proxy::<TcpConnector>::new("")
    .with_config(ClientConfig { //<-
        nodelay: Some(true),

chainable constructor to specfiy a Client to use. This is useful if the application already is using trillium_client for other requests, as it will reuse the same connection pool and connector config.

note that this clears out any changes made with Proxy::with_config. configure the client directly if you are providing one

use trillium_smol::{TcpConnector, ClientConfig};
use trillium_proxy::{Proxy, Client};

let client = Client::new().with_default_pool();
let proxy = Proxy::<TcpConnector>::new("")
    .with_client(client); //<-
// sharing a client with other trillium handlers
use trillium::State;

let client = Client::new().with_default_pool();
let handler = (

chainable constructor to set the 404 Not Found handling behavior. By default, this proxy will pass through the trillium Conn unmodified if the proxy response is a 404 not found, allowing it to be chained in a tuple handler. To modify this behavior, call proxy_not_found, and the full 404 response will be forwarded. The Conn will be halted unless Proxy::without_halting was configured

let proxy = Proxy::<TcpConnector>::new("")

The default behavior for this handler is to halt the conn on any response other than a 404. If Proxy::proxy_not_found has been configured, the default behavior for all response statuses is to halt the trillium conn. To change this behavior, call without_halting when constructing the proxy, and it will not halt the conn. This is useful when passing the proxy reply through trillium_html_rewriter.

let proxy = Proxy::<TcpConnector>::new("")

Trait Implementations

Formats the value using the given formatter. Read more
Executes this handler, performing any modifications to the Conn that are desired. Read more
predicate function answering the question of whether this Handler would like to take ownership of the negotiated Upgrade. If this returns true, you must implement [Handler::upgrade]. The first handler that responds true to this will receive ownership of the [trillium::Upgrade][crate::Upgrade] in a subsequent call to [Handler::upgrade] Read more
This will only be called if the handler reponds true to [Handler::has_upgrade] and will only be called once for this upgrade. There is no return value, and this function takes exclusive ownership of the underlying transport once this is called. You can downcast the transport to whatever the source transport type is and perform any non-http protocol communication that has been negotiated. You probably don’t want this unless you’re implementing something like websockets. Please note that for many transports such as TcpStreams, dropping the transport (and therefore the Upgrade) will hang up / disconnect. Read more
Performs one-time async set up on a mutable borrow of the Handler before the server starts accepting requests. This allows a Handler to be defined in synchronous code but perform async setup such as establishing a database connection or fetching some state from an external source. This is optional, and chances are high that you do not need this. Read more
Performs any final modifications to this conn after all handlers have been run. Although this is a slight deviation from the simple conn->conn->conn chain represented by most Handlers, it provides an easy way for libraries to effectively inject a second handler into a response chain. This is useful for loggers that need to record information both before and after other handlers have run, as well as database transaction handlers and similar library code. Read more
Customize the name of your handler. This is used in Debug implementations. The default is the type name of this handler. Read more
