Struct hyper_util::client::legacy::connect::HttpConnector

source ·
pub struct HttpConnector<R = GaiResolver> { /* private fields */ }
Expand description

A connector for the http scheme.

Performs DNS resolution in a thread pool, and then connects over TCP.

§Note

Sets the HttpInfo value on responses, which includes transport information such as the remote socket address used.

Implementations§

source§

impl HttpConnector

source

pub fn new() -> HttpConnector

Construct a new HttpConnector.

source§

impl<R> HttpConnector<R>

source

pub fn new_with_resolver(resolver: R) -> HttpConnector<R>

Construct a new HttpConnector.

Takes a Resolver to handle DNS lookups.

source

pub fn enforce_http(&mut self, is_enforced: bool)

Option to enforce all Uris have the http scheme.

Enabled by default.

source

pub fn set_keepalive(&mut self, time: Option<Duration>)

Set that all sockets have SO_KEEPALIVE set with the supplied duration to remain idle before sending TCP keepalive probes.

If None, keepalive is disabled.

Default is None.

source

pub fn set_keepalive_interval(&mut self, interval: Option<Duration>)

Set the duration between two successive TCP keepalive retransmissions, if acknowledgement to the previous keepalive transmission is not received.

source

pub fn set_keepalive_retries(&mut self, retries: Option<u32>)

Set the number of retransmissions to be carried out before declaring that remote end is not available.

source

pub fn set_nodelay(&mut self, nodelay: bool)

Set that all sockets have SO_NODELAY set to the supplied value nodelay.

Default is false.

source

pub fn set_send_buffer_size(&mut self, size: Option<usize>)

Sets the value of the SO_SNDBUF option on the socket.

source

pub fn set_recv_buffer_size(&mut self, size: Option<usize>)

Sets the value of the SO_RCVBUF option on the socket.

source

pub fn set_local_address(&mut self, addr: Option<IpAddr>)

Set that all sockets are bound to the configured address before connection.

If None, the sockets will not be bound.

Default is None.

source

pub fn set_local_addresses(&mut self, addr_ipv4: Ipv4Addr, addr_ipv6: Ipv6Addr)

Set that all sockets are bound to the configured IPv4 or IPv6 address (depending on host’s preferences) before connection.

source

pub fn set_connect_timeout(&mut self, dur: Option<Duration>)

Set the connect timeout.

If a domain resolves to multiple IP addresses, the timeout will be evenly divided across them.

Default is None.

source

pub fn set_happy_eyeballs_timeout(&mut self, dur: Option<Duration>)

Set timeout for RFC 6555 (Happy Eyeballs) algorithm.

If hostname resolves to both IPv4 and IPv6 addresses and connection cannot be established using preferred address family before timeout elapses, then connector will in parallel attempt connection using other address family.

If None, parallel connection attempts are disabled.

Default is 300 milliseconds.

source

pub fn set_reuse_address(&mut self, reuse_address: bool) -> &mut Self

Set that all socket have SO_REUSEADDR set to the supplied value reuse_address.

Default is false.

source

pub fn set_interface<S: Into<String>>(&mut self, interface: S) -> &mut Self

Sets the value for the SO_BINDTODEVICE option on this socket.

If a socket is bound to an interface, only packets received from that particular interface are processed by the socket. Note that this only works for some socket types, particularly AF_INET sockets.

On Linux it can be used to specify a VRF, but the binary needs to either have CAP_NET_RAW or to be run as root.

This function is only available on Android、Fuchsia and Linux.
