Struct TapBackend 

pub struct TapBackend { /* private fields */ }

TAP network backend for Linux.

Implementations

impl TapBackend

pub fn new(name: Option<&str>) -> Result<TapBackend, Error>

Creates a new TAP device.

Errors

Returns an error if TAP device creation fails.

pub fn set_nonblocking(&mut self, nonblocking: bool) -> Result<(), Error>

Sets non-blocking mode.

pub fn name(&self) -> &str

Returns the TAP device name.

pub fn bring_up(&self) -> Result<(), Error>

Brings the interface up.

pub fn set_ip(&self, ip: &str, prefix_len: u8) -> Result<(), Error>

Sets the IP address.

Trait Implementations

impl Drop for TapBackend

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl NetBackend for TapBackend

fn send(&mut self, packet: &NetPacket) -> Result<usize, Error>

Sends a packet.

fn recv(&mut self, buf: &mut [u8]) -> Result<usize, Error>

Receives a packet.

fn has_data(&self) -> bool

Returns whether packets are available to receive.

fn configure_offload(&mut self, flags: NetOffloadFlags) -> Result<(), Error>

Configure host-side offload to match the features the guest negotiated.

fn set_vnet_hdr_sz(&mut self, size: u32) -> Result<(), Error>

Configure the size of the virtio_net_hdr prepended to each frame on the backend’s wire representation.

fn send_tso(&mut self, packet: &NetPacket) -> Result<usize, Error>

Sends a TSO/GSO packet.

fn supports_tso(&self) -> bool

Returns whether this backend supports TSO offload.
