Struct hyper::server::conn::Http

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

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

pub fn new() -> Http

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

impl<E> Http<E>

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

Sets whether HTTP1 is required.

Default is false

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

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

Enables or disables HTTP/1 keep-alive.

Default is true.

pub fn http1_title_case_headers(&mut self, enabled: bool) -> &mut Self

Set whether HTTP/1 connections will write header names as title case at the socket level.

Note that this setting does not affect HTTP/2.

Default is false.

pub fn http1_preserve_header_case(&mut self, enabled: bool) -> &mut Self

Set whether to support preserving original header cases.

Currently, this will record the original cases received, and store them in a private extension on the Request. It will also look for and use such an extension in any provided Response.

Since the relevant extension is still private, there is no way to interact with the original cases. The only effect this can have now is to forward the cases in a proxy-like fashion.

Note that this setting does not affect HTTP/2.

Default is false.

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

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 max_buf_size(&mut self, max: usize) -> &mut Self

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

Aggregates flushes to better support pipelined responses.

Experimental, may have bugs.

Default is false.

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

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>

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: ConnStreamExec<S::Future, Bd>,

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);
}

Trait Implementations

impl<E: Clone> Clone for Http<E>

fn clone(&self) -> Http<E>

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

Performs copy-assignment from source.
