Struct PushQueue 

pub struct PushQueue<Prev: Pusher> { /* private fields */ }

Available on crate feature netdev only.

Implementations

impl<Prev: Pusher> PushQueue<Prev>

pub fn new(prev: Prev) -> Self

pub fn end_nested(self) -> Prev

pub fn push_id(self, value: u32) -> Self

Queue index; most queue types are indexed like a C array, with indexes starting at 0 and ending at queue count - 1. Queue indexes are scoped to an interface and queue type.

pub fn push_ifindex(self, value: u32) -> Self

ifindex of the netdevice to which the queue belongs.

pub fn push_type(self, value: u32) -> Self

Queue type as rx, tx. Each queue type defines a separate ID space. XDP TX queues allocated in the kernel are not linked to NAPIs and thus not listed. AF_XDP queues will have more information set in the xsk attribute.

Associated type: QueueType (enum)

pub fn push_napi_id(self, value: u32) -> Self

ID of the NAPI instance which services this queue.

pub fn push_dmabuf(self, value: u32) -> Self

ID of the dmabuf attached to this queue, if any.

pub fn nested_io_uring(self) -> PushIoUringProviderInfo<Self>

io_uring memory provider information.

pub fn nested_xsk(self) -> PushXskInfo<Self>

XSK information for this queue, if any.

pub fn nested_lease(self) -> PushLease<Self>

A queue from a virtual device can have a lease which refers to another queue from a physical device. This is useful for memory providers and AF_XDP operations which take an ifindex and queue id to allow applications to bind against virtual devices in containers.

Trait Implementations

impl<Prev: Pusher> Drop for PushQueue<Prev>

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<Prev: Pusher> Pusher for PushQueue<Prev>

fn as_vec_mut(&mut self) -> &mut Vec<u8>

fn as_vec(&self) -> &Vec<u8>

fn as_rec(&self) -> &Vec<u8>

👎Deprecated:

Use .as_vec() instead (rec -> vec)

fn as_rec_mut(&mut self) -> &mut Vec<u8>

👎Deprecated:

Use .as_vec_mut() instead (rec -> vec)
