Enum RingMode 

pub enum RingMode {
    Standard,
    SqPoll,
    IoPoll,
    SqPollIoPoll,
}

Ring operation mode.

Variants

Standard

Standard mode with interrupt-based completions.

SqPoll

SQPOLL mode with kernel polling thread (no syscalls under load).

IoPoll

IOPOLL mode for NVMe devices (polls completions from device). Cannot be used with socket operations.

SqPollIoPoll

Combined SQPOLL + IOPOLL for maximum performance on NVMe.

Implementations

impl RingMode

pub const fn uses_sqpoll(&self) -> bool

Returns true if SQPOLL is enabled.

pub const fn uses_iopoll(&self) -> bool

Returns true if IOPOLL is enabled.

Trait Implementations

impl Clone for RingMode

fn clone(&self) -> RingMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RingMode

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

Formats the value using the given formatter.

impl Default for RingMode

fn default() -> RingMode

Returns the “default value” for a type.

impl PartialEq for RingMode

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

impl Copy for RingMode
