Struct RawCompletionQueueEntry 

#[repr(C)]
pub struct RawCompletionQueueEntry {
    pub user_data: u64,
    pub res: i32,
    pub flags: u32,
}

Miroir exact de struct io_uring_cqe (16 octets). Le big_cqe[] (16 o supplémentaires) de SETUP_CQE32 n’est pas exposé. L’interprétation de res/flags est à la charge de l’appelant (selon l’opcode soumis).

Fields

user_data: u64

user_data de l’op (avec RAW_USER_DATA_TAG pour une op brute, §5).

res: i32

Résultat brut : -errno si négatif, valeur utile (fd, octets…) sinon.

flags: u32

Flags IORING_CQE_F_* (+ id de buffer dans les bits hauts).

Trait Implementations

impl Clone for RawCompletionQueueEntry

fn clone(&self) -> RawCompletionQueueEntry

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RawCompletionQueueEntry

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for RawCompletionQueueEntry

fn eq(&self, other: &RawCompletionQueueEntry) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
