Struct hyper::server::conn::Http [−][src]
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]
&mut self,
sz: impl Into<Option<u32>>
) -> &mut Self
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]
&mut self,
sz: impl Into<Option<u32>>
) -> &mut Self
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]
&mut self,
max: impl Into<Option<u32>>
) -> &mut Self
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]
&mut self,
interval: impl Into<Option<Duration>>
) -> &mut Self
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
).
