Struct mio_httpc::CallBuilder

pub struct CallBuilder {}

Used to start a call and get a Call for it.

Methods

impl CallBuilder

fn new(req: Request<Vec<u8>>) -> CallBuilder

If req contains body it will be used.

If req contains no body, but has content-length set, it will wait for send body to be provided through Httpc::call_send. mio_httpc will set headers (if they are not already): user-agent, connection, host, auth, content-length If you're only executing a one-off call you should set connection: close as default is keep-alive.

fn call(self, httpc: &mut Httpc, poll: &Poll) -> Result<Call>

Consume and execute HTTP call

fn websocket(self, httpc: &mut Httpc, poll: &Poll) -> Result<WebSocket>

Consume and start a WebSocket

fn add_root_ca_der(self, v: Vec<u8>) -> Self

Add custom root ca in DER format

fn max_response(self, m: usize) -> Self

Default 10MB.

This will limit how big the internal Vec can grow. HTTP response headers are always stored in internal buffer. HTTP response body is stored in internal buffer if no external buffer is provided.

For WebSockets this will also be a received fragment size limit!

fn dns_retry_ms(self, n: u64) -> Self

Default: 100ms

Starting point of dns packet resends if nothing received. Every next resend timeout is 2x the previous one but stops at 1s. So for 100ms: 100ms, 200ms, 400ms, 800ms, 1000ms, 1000ms...

fn chunked_parse(self, b: bool) -> Self

Default true.

Configurable because it entails copying the data stream.

fn chunked_max_chunk(self, v: usize) -> Self

Default 32K

Max size of chunk in a chunked transfer.

fn timeout_ms(self, d: u64) -> Self

Default 60s

Maximum amount of time a call should last.
