Enum RegisterOp 

#[non_exhaustive]
pub enum RegisterOp {
    Buffers,
    Files,
    Eventfd,
    Personality,
    ProvidedBuffers,
    RingFd,
    SyncCancel,
    Probe,
}

Register opcode qu’un ring confiné peut être autorisé à effectuer (RESTRICTION_REGISTER_OP). Newtype typé plutôt qu’un u8 magique (ADR-021 conv. 3 : chaque opération est une variante nommée). #[non_exhaustive] : de futurs kernels peuvent en ajouter.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Buffers

IORING_REGISTER_BUFFERS2 (15) — buffers enregistrés (Temps 3a).

Files

IORING_REGISTER_FILES2 (13) — table de FD fixes (Temps 3a).

Eventfd

IORING_REGISTER_EVENTFD (4) — eventfd de complétion (Temps 3a).

Personality

IORING_REGISTER_PERSONALITY (9) — identité enregistrée (Temps 3a).

ProvidedBuffers

IORING_REGISTER_PBUF_RING (22) — buffers fournis ring-mapped (Temps 3b).

RingFd

IORING_REGISTER_RING_FDS (20) — enregistrement du ring fd (Temps 3a/3e).

Probe

IORING_REGISTER_PROBE (8) — introspection des opcodes (Temps 1).

Trait Implementations

impl Clone for RegisterOp

fn clone(&self) -> RegisterOp

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RegisterOp

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

Formats the value using the given formatter.

impl PartialEq for RegisterOp

fn eq(&self, other: &RegisterOp) -> 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.
