Enum RingEventFlags

#[non_exhaustive]
#[repr(u8)]
pub enum RingEventFlags {
    Enable = 0,
    Disable = 1,
    Desc = 2,
    Reserved = 3,
}

Descriptor Ring Change Event Flags

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.

Enable = 0

Enable events

Disable = 1

Disable events

Desc = 2

Enable events for a specific descriptor (as specified by Descriptor Ring Change Event Offset/Wrap Counter). Only valid if VIRTIO_F_EVENT_IDX has been negotiated.

Reserved = 3

Trait Implementations

impl Clone for RingEventFlags

fn clone(&self) -> RingEventFlags

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RingEventFlags

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

Formats the value using the given formatter.

impl From<RingEventFlags> for u8

fn from(enum_value: RingEventFlags) -> Self

Converts to this type from the input type.

impl PartialEq for RingEventFlags

fn eq(&self, other: &RingEventFlags) -> 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 TryFrom<u8> for RingEventFlags

type Error = TryFromPrimitiveError<RingEventFlags>

The type returned in the event of a conversion error.

fn try_from(number: u8) -> Result<Self, TryFromPrimitiveError<Self>>

Performs the conversion.

impl TryFromPrimitive for RingEventFlags

const NAME: &'static str = "RingEventFlags"

type Primitive = u8

type Error = TryFromPrimitiveError<RingEventFlags>

fn try_from_primitive( number: Self::Primitive, ) -> Result<Self, TryFromPrimitiveError<Self>>

impl Copy for RingEventFlags
