Struct reqwest::Client

pub struct Client { /* private fields */ }

An asynchronous Client to make Requests with.

The Client has various configuration values to tweak, but the defaults are set to what is usually the most commonly desired value. To configure a Client, use Client::builder().

The Client holds a connection pool internally, so it is advised that you create one and reuse it.

You do not have to wrap the Client in an Rc or Arc to reuse it, because it already uses an Arc internally.

Implementations

impl Client

pub fn new() -> Client

Constructs a new Client.

Panics

This method panics if a TLS backend cannot be initialized, or the resolver cannot load the system configuration.

Use Client::builder() if you wish to handle the failure as an Error instead of panicking.

pub fn builder() -> ClientBuilder

Creates a ClientBuilder to configure a Client.

This is the same as ClientBuilder::new().

pub fn get<U: IntoUrl>(&self, url: U) -> RequestBuilder

Convenience method to make a GET request to a URL.

Errors

This method fails whenever the supplied Url cannot be parsed.

pub fn post<U: IntoUrl>(&self, url: U) -> RequestBuilder

Convenience method to make a POST request to a URL.

Errors

This method fails whenever the supplied Url cannot be parsed.

pub fn put<U: IntoUrl>(&self, url: U) -> RequestBuilder

Convenience method to make a PUT request to a URL.

Errors

This method fails whenever the supplied Url cannot be parsed.

pub fn patch<U: IntoUrl>(&self, url: U) -> RequestBuilder

Convenience method to make a PATCH request to a URL.

Errors

This method fails whenever the supplied Url cannot be parsed.

pub fn delete<U: IntoUrl>(&self, url: U) -> RequestBuilder

Convenience method to make a DELETE request to a URL.

Errors

This method fails whenever the supplied Url cannot be parsed.

pub fn head<U: IntoUrl>(&self, url: U) -> RequestBuilder

Convenience method to make a HEAD request to a URL.

Errors

This method fails whenever the supplied Url cannot be parsed.

pub fn request<U: IntoUrl>(&self, method: Method, url: U) -> RequestBuilder

Start building a Request with the Method and Url.

Returns a RequestBuilder, which will allow setting headers and the request body before sending.

Errors

This method fails whenever the supplied Url cannot be parsed.

pub fn execute( &self, request: Request ) -> impl Future<Output = Result<Response, Error>>

Executes a Request.

A Request can be built manually with Request::new() or obtained from a RequestBuilder with RequestBuilder::build().

You should prefer to use the RequestBuilder and RequestBuilder::send().

Errors

This method fails if there was an error while sending request, redirect loop was detected or redirect limit was exhausted.

Trait Implementations

impl Clone for Client

fn clone(&self) -> Client

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Client

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Client

fn default() -> Self

Returns the “default value” for a type.

impl Service<Request> for &Client

type Response = Response

Responses given by the service.

type Error = Error

Errors produced by the service.

type Future = Pending

The future response value.

fn poll_ready(&mut self, _cx: &mut Context<'_>) -> Poll<Result<(), Self::Error>>

Returns Poll::Ready(Ok(())) when the service is able to process requests.

fn call(&mut self, req: Request) -> Self::Future

Process the request and return the response asynchronously.

impl Service<Request> for Client

type Response = Response
