Struct reverse_proxy_service::OneshotService

source · 
pub struct OneshotService<Pr, C = HttpConnector, B = Body> { /* private fields */ }
Available on crate features http1 or http2 only.
Expand description

A Service<Request<B>> that sends a request and returns the response, owning a Client.

let mut svc = OneshotService::http_default("example.com:1234", Static("bar")).unwrap();
let req = Request::builder()
    .uri("https://myserver.com/foo")
    .body(Body::empty())
    .unwrap();
// http://example.com:1234/bar
let _res = svc.call(req).await.unwrap();

Implementations§

source§

impl<Pr, C, B> OneshotService<Pr, C, B>

source

pub fn from<S, A>( client: Client<C, B>, scheme: S, authority: A, path: Pr ) -> Result<Self, HttpError>where Scheme: TryFrom<S>, <Scheme as TryFrom<S>>::Error: Into<HttpError>, Authority: TryFrom<A>, <Authority as TryFrom<A>>::Error: Into<HttpError>,

Initializes a service with a general Client.

A client can be built by functions in client.

For the meaning of “scheme” and “authority”, refer to the documentation of Uri.

The path should implement PathRewriter.

impl<Pr, B> OneshotService<Pr, HttpConnector, B>where B: HttpBody + Send, B::Data: Send,

source

pub fn http_default<A>(authority: A, path: Pr) -> Result<Self, HttpError>where Authority: TryFrom<A>, <Authority as TryFrom<A>>::Error: Into<HttpError>,

Use client::http_default() to build a client.

For the meaning of “authority”, refer to the documentation of Uri.

The path should implement PathRewriter.

source§

impl<Pr, B> OneshotService<Pr, HttpsConnector<HttpConnector>, B>where B: HttpBody + Send, B::Data: Send,

source

pub fn https_default<A>(authority: A, path: Pr) -> Result<Self, HttpError>where Authority: TryFrom<A>, <Authority as TryFrom<A>>::Error: Into<HttpError>,

Available on crate feature https only.

Use client::https_default() to build a client.

For the meaning of “authority”, refer to the documentation of Uri.

The path should implement PathRewriter.
