Struct ProvidedBufRing 

pub struct ProvidedBufRing { /* private fields */ }

A registered provided-buffer ring (the destination pool for multishot recv). Owns the buf-ring mapping and the backing slab; the kernel fills a buffer per arrival, the app recycles it.

Implementations

impl ProvidedBufRing

pub fn group(&self) -> u16

The buffer group id this ring serves (pass to prep_recv_multishot).

pub fn bytes(&self, bid: u16, n: usize) -> &[u8]

The n valid bytes the kernel placed in buffer bid (n = completion res).

pub fn recycle(&mut self, bid: u16)

Return buffer bid to the ring so the kernel can reuse it. Call once the bytes from its completion have been copied out.

Trait Implementations

impl Drop for ProvidedBufRing

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.
