Struct devices::virtio::vhost::user::device::VhostUserListener

pub struct VhostUserListener(SocketListener);

On Unix we can listen to a socket.

Tuple Fields

0: SocketListener

Implementations

impl VhostUserListener

pub fn new_socket( path: &str, keep_rds: Option<&mut Vec<RawDescriptor>> ) -> Result<Self>

Creates a new regular vhost-user listener, listening on path.

keep_rds can be specified to retrieve the raw descriptors that must be preserved for this listener to keep working after forking.

Trait Implementations

impl VhostUserListenerTrait for VhostUserListener

fn new(path: &str, keep_rds: Option<&mut Vec<RawDescriptor>>) -> Result<Self>

Create a vhost-user listener from a UNIX domain socket path.

keep_rds can be specified to retrieve the raw descriptors that must be preserved for this listener to keep working after forking.

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 listener. Returns when the front-end side disconnects or an error occurs.
