Connection from connected socket

Tuple Fields

Implementations

impl VhostUserStream

pub fn new_socket_from_fd(socket_fd: RawDescriptor) -> Result<Self>

Creates a new vhost-user listener from an existing connected socket file descriptor.

Errors

Returns an error if:

• The provided file descriptor is not a socket.
• An error occurs while creating the underlying SocketListener.

Trait Implementations

impl AsRawDescriptor for VhostUserStream

fn as_raw_descriptor(&self) -> RawDescriptor

Returns the underlying raw descriptor.

impl VhostUserConnectionTrait for VhostUserStream

fn run_req_handler<'e>( self, handler: Box<dyn Backend>, ex: &'e Executor, ) -> Pin<Box<dyn Future<Output = Result<()>> + 'e>>

Returns a Future that processes requests for handler. The future exits when the front-end side disconnects or an error occurs.

fn take_parent_process_resources(&mut self) -> Option<Box<dyn Any>>

Take and return resources owned by the parent process in case of a incoming fork.

fn run_backend<'e>( self, backend: impl VhostUserDevice + 'static, ex: &'e Executor, ) -> Pin<Box<dyn Future<Output = Result<()>> + 'e>>

where Self: Sized,

Returns a Future that will process requests from backend when polled. The future exits when the front-end side disconnects or an error occurs.

fn run_device( self, ex: Executor, device: Box<dyn VhostUserDeviceBuilder>, ) -> Result<()>

where Self: Sized,

Start processing requests for a VhostUserDevice on connection. Returns when the front-end side disconnects or an error occurs.
