Struct awc::ClientBuilder

pub struct ClientBuilder<S = (), M = ()> { /* private fields */ }

An HTTP Client builder

This type can be used to construct an instance of Client through a builder-like pattern.

Implementations

impl ClientBuilder

pub fn new( ) -> ClientBuilder<impl Service<ConnectInfo<Uri>, Response = TcpConnection<Uri, TcpStream>, Error = TcpConnectError> + Clone, ()>

impl<S, Io, M> ClientBuilder<S, M>where S: Service<ConnectInfo<Uri>, Response = TcpConnection<Uri, Io>, Error = TcpConnectError> + Clone + 'static, Io: ActixStream + Debug + 'static,

pub fn connector<S1, Io1>(self, connector: Connector<S1>) -> ClientBuilder<S1, M>where S1: Service<ConnectInfo<Uri>, Response = TcpConnection<Uri, Io1>, Error = TcpConnectError> + Clone + 'static, Io1: ActixStream + Debug + 'static,

Use custom connector service.

pub fn timeout(self, timeout: Duration) -> Self

Set request timeout

Request timeout is the total time before a response must be received. Default value is 5 seconds.

pub fn disable_timeout(self) -> Self

Disable request timeout.

pub fn local_address(self, addr: IpAddr) -> Self

Set local IP Address the connector would use for establishing connection.

pub fn max_http_version(self, val: Version) -> Self

Maximum supported HTTP major version.

Supported versions are HTTP/1.1 and HTTP/2.

pub fn disable_redirects(self) -> Self

Do not follow redirects.

Redirects are allowed by default.

pub fn max_redirects(self, num: u8) -> Self

Set max number of redirects.

Max redirects is set to 10 by default.

pub fn initial_window_size(self, size: u32) -> Self

Indicates the initial window size (in octets) for HTTP2 stream-level flow control for received data.

The default value is 65,535 and is good for APIs, but not for big objects.

pub fn initial_connection_window_size(self, size: u32) -> Self

Indicates the initial window size (in octets) for HTTP2 connection-level flow control for received data.

The default value is 65,535 and is good for APIs, but not for big objects.

pub fn no_default_headers(self) -> Self

Do not add fundamental default request headers.

By default Date and User-Agent headers are set.

pub fn add_default_header(self, header: impl TryIntoHeaderPair) -> Self

Add default header.

Headers added by this method get added to every request unless overridden by other methods.

Panics

Panics if header name or value is invalid.

pub fn basic_auth<N>(self, username: N, password: Option<&str>) -> Selfwhere N: Display,

Set client wide HTTP basic authorization header

pub fn bearer_auth<T>(self, token: T) -> Selfwhere T: Display,

Set client wide HTTP bearer authentication header

pub fn wrap<S1, M1>( self, mw: M1 ) -> ClientBuilder<S, NestTransform<M, M1, S1, ConnectRequest>>where M: Transform<S1, ConnectRequest>, M1: Transform<M::Transform, ConnectRequest>,

Registers middleware, in the form of a middleware component (type), that runs during inbound and/or outbound processing in the request life-cycle (request -> response), modifying request/response as necessary, across all requests managed by the Client.

pub fn finish(self) -> Clientwhere M: Transform<DefaultConnector<ConnectorServicePriv<TcpConnectorService<TcpConnectorInnerService<S>>, Rc<dyn Service<Connect, Response = (Box<dyn ConnectionIo>, Protocol), Error = ConnectError, Future = LocalBoxFuture<'static, Result<(Box<dyn ConnectionIo>, Protocol), ConnectError>>>>, Io, Box<dyn ConnectionIo>>>, ConnectRequest> + 'static, M::Transform: Service<ConnectRequest, Response = ConnectResponse, Error = SendRequestError>,

Finish build process and create Client instance.
