Struct trillium_http::transport::BoxedTransport
source · pub struct BoxedTransport(/* private fields */);
Expand description
§A type for dyn Transport
trait objects
BoxedTransport
represents a Box<dyn Transport + Any>
that supports
downcasting to the original Transport. This is used in trillium to
erase the generic on Conn, in order to avoid writing Conn<TcpStream>
throughout an application.
Stability Note: This may go away at some point and be
replaced by a type alias exported from a
trillium_server_common::Server
crate.
Implementations§
source§impl BoxedTransport
impl BoxedTransport
sourcepub fn new<T: Transport + Any>(t: T) -> Self
pub fn new<T: Transport + Any>(t: T) -> Self
Create a new BoxedTransport
from some Transport.
use trillium_http::transport::BoxedTransport;
use trillium_testing::TestTransport;
// this examples uses trillium_testing::TestTransport as an
// easily-constructed AsyncRead+AsyncWrite.
let (test_transport, _) = TestTransport::new();
let boxed = BoxedTransport::new(test_transport);
let downcast: Option<Box<TestTransport>> = boxed.downcast();
assert!(downcast.is_some());
let boxed_again = BoxedTransport::new(*downcast.unwrap());
assert!(boxed_again.downcast::<async_net::TcpStream>().is_none());
sourcepub fn downcast<T: 'static>(self) -> Option<Box<T>>
pub fn downcast<T: 'static>(self) -> Option<Box<T>>
Attempt to convert the trait object into a specific transport
T. This will only succeed if T is the type that was originally
passed to BoxedTransport::new
, and will return None otherwise
see BoxedTransport::new
for example usage
sourcepub fn downcast_ref<T: Transport>(&self) -> Option<&T>
pub fn downcast_ref<T: Transport>(&self) -> Option<&T>
Attempt to get a reference to the trait object as a specific transport type T. This will only
succeed if T is the type that was originally passed to BoxedTransport::new
, and will return
None otherwise
sourcepub fn downcast_mut<T: Transport>(&mut self) -> Option<&mut T>
pub fn downcast_mut<T: Transport>(&mut self) -> Option<&mut T>
Attempt to get a mutable reference to the trait object as a specific transport type T. This
will only succeed if T is the type that was originally passed to BoxedTransport::new
, and
will return None otherwise
