Struct hyper::server::conn::Http[][src]

pub struct Http<E = Exec> { /* fields omitted */ }

A lower-level configuration of the HTTP protocol.

This structure is used to configure options for an HTTP server connection.

If you don’t have need to manage connections yourself, consider using the higher-level Server API.

Implementations

impl Http[src]

pub fn new() -> Http[src]

Creates a new instance of the HTTP protocol, ready to spawn a server or start accepting connections.

impl<E> Http<E>[src]

pub fn http1_only(&mut self, val: bool) -> &mut Self[src]

Sets whether HTTP1 is required.

Default is false

pub fn http1_half_close(&mut self, val: bool) -> &mut Self[src]

Set whether HTTP/1 connections should support half-closures.

Clients can chose to shutdown their write-side while waiting for the server to respond. Setting this to true will prevent closing the connection immediately if read detects an EOF in the middle of a request.

Default is false.

pub fn http1_keep_alive(&mut self, val: bool) -> &mut Self[src]

Enables or disables HTTP/1 keep-alive.

Default is true.

pub fn http1_writev(&mut self, val: bool) -> &mut Self[src]

Set whether HTTP/1 connections should try to use vectored writes, or always flatten into a single buffer.

Note that setting this to false may mean more copies of body data, but may also improve performance when an IO transport doesn’t support vectored writes well, such as most TLS implementations.

Setting this to true will force hyper to use queued strategy which may eliminate unnecessary cloning on some TLS backends

Default is auto. In this mode hyper will try to guess which mode to use

pub fn http2_only(&mut self, val: bool) -> &mut Self[src]

Sets whether HTTP2 is required.

Default is false

pub fn http2_initial_stream_window_size(
    &mut self,
    sz: impl Into<Option<u32>>
) -> &mut Self
[src]

Sets the SETTINGS_INITIAL_WINDOW_SIZE option for HTTP2 stream-level flow control.

Passing None will do nothing.

If not set, hyper will use a default.

pub fn http2_initial_connection_window_size(
    &mut self,
    sz: impl Into<Option<u32>>
) -> &mut Self
[src]

Sets the max connection-level flow control for HTTP2.

Passing None will do nothing.

If not set, hyper will use a default.

pub fn http2_adaptive_window(&mut self, enabled: bool) -> &mut Self[src]

Sets whether to use an adaptive flow control.

Enabling this will override the limits set in http2_initial_stream_window_size and http2_initial_connection_window_size.

pub fn http2_max_frame_size(&mut self, sz: impl Into<Option<u32>>) -> &mut Self[src]

Sets the maximum frame size to use for HTTP2.

Passing None will do nothing.

If not set, hyper will use a default.

pub fn http2_max_concurrent_streams(
    &mut self,
    max: impl Into<Option<u32>>
) -> &mut Self
[src]

Sets the SETTINGS_MAX_CONCURRENT_STREAMS option for HTTP2 connections.

Default is no limit (std::u32::MAX). Passing None will do nothing.

pub fn http2_keep_alive_interval(
    &mut self,
    interval: impl Into<Option<Duration>>
) -> &mut Self
[src]

Sets an interval for HTTP2 Ping frames should be sent to keep a connection alive.

Pass None to disable HTTP2 keep-alive.

Default is currently disabled.

Cargo Feature

Requires the runtime cargo feature to be enabled.

pub fn http2_keep_alive_timeout(&mut self, timeout: Duration) -> &mut Self[src]

Sets a timeout for receiving an acknowledgement of the keep-alive ping.

If the ping is not acknowledged within the timeout, the connection will be closed. Does nothing if http2_keep_alive_interval is disabled.

Default is 20 seconds.

Cargo Feature

Requires the runtime cargo feature to be enabled.

pub fn max_buf_size(&mut self, max: usize) -> &mut Self[src]

Set the maximum buffer size for the connection.

Default is ~400kb.

Panics

The minimum value allowed is 8192. This method panics if the passed max is less than the minimum.

pub fn pipeline_flush(&mut self, enabled: bool) -> &mut Self[src]

Aggregates flushes to better support pipelined responses.

Experimental, may have bugs.

Default is false.

pub fn with_executor<E2>(self, exec: E2) -> Http<E2>[src]

Set the executor used to spawn background tasks.

Default uses implicit default (like tokio::spawn).

pub fn serve_connection<S, I, Bd>(
    &self,
    io: I,
    service: S
) -> Connection<I, S, E>

Notable traits for Connection<I, S, E>

impl<I, B, S, E> Future for Connection<I, S, E> where
    S: HttpService<Body, ResBody = B>,
    S::Error: Into<Box<dyn StdError + Send + Sync>>,
    I: AsyncRead + AsyncWrite + Unpin + 'static,
    B: HttpBody + 'static,
    B::Error: Into<Box<dyn StdError + Send + Sync>>,
    E: H2Exec<S::Future, B>, 
type Output = Result<()>;
where
    S: HttpService<Body, ResBody = Bd>,
    S::Error: Into<Box<dyn StdError + Send + Sync>>,
    Bd: HttpBody + 'static,
    Bd::Error: Into<Box<dyn StdError + Send + Sync>>,
    I: AsyncRead + AsyncWrite + Unpin,
    E: H2Exec<S::Future, Bd>, 
[src]

Bind a connection together with a Service.

This returns a Future that must be polled in order for HTTP to be driven on the connection.

Example

let http = Http::new();
let conn = http.serve_connection(some_io, some_service);

if let Err(e) = conn.await {
    eprintln!("server connection error: {}", e);
}
