Structs

• BlockOptions
  Block device
• ConsoleOptions
  Console device
• FsOptions
  FS Device
• NetBackend
• NetOptions
  Net device
• VhostUserListener
  On Unix we can listen to a socket.
• VhostUserStream
  Connection from connected socket
• VhostUserVsockDevice
  A vhost-vsock device which handle is already opened. This allows the parent process to open the vhost-vsock device, create this structure, and pass it to the child process so it doesn’t need the rights to open the vhost-vsock device itself.
• VsockOptions
  Vsock device
• WlOptions
  Wayland device

Enums

• BackendConnection

Traits

• VhostUserConnectionTrait
  Trait that the platform-specific type VhostUserConnection needs to implement. It contains all the methods that are ok to call from non-platform specific code.
• VhostUserDevice
  Trait for vhost-user devices. Analogous to the VirtioDevice trait.
• VhostUserDeviceBuilder
  A trait for not-yet-built vhost-user devices.

Functions

• create_vu_console_device
  Return a new vhost-user console device. params are the device’s configuration, and keep_rds is a vector into which RawDescriptors that need to survive a fork are added, in case the device is meant to run within a child process.
• parse_wayland_sock
• run_block_device
  Starts a vhost-user block device. Returns an error if the given args is invalid or the device fails to run.
• run_console_device
  Starts a vhost-user console device. Returns an error if the given args is invalid or the device fails to run.
• run_fs_device
  Starts a vhost-user fs device. Returns an error if the given args is invalid or the device fails to run.
• run_net_device
  Starts a vhost-user net device. Returns an error if the given args is invalid or the device fails to run.
• run_vsock_device
  Returns an error if the given args is invalid or the device fails to run.
• run_wl_device
  Starts a vhost-user wayland device. Returns an error if the given args is invalid or the device fails to run.
