Variants

Add = 0

Unknown = 3

Unknown.

Trait Implementations

impl Clone for EpollCtl

fn clone(&self) -> EpollCtl

Returns a copy of the value.

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

Performs copy-assignment from source.

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for EpollCtl

fn deserialize<__D>( __deserializer: __D, ) -> Result<EpollCtl, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<&ArchivedJournalEpollCtlV1> for EpollCtl

fn from(val: &ArchivedJournalEpollCtlV1) -> EpollCtl

Converts to this type from the input type.

impl From<EpollCtl> for JournalEpollCtlV1

fn from(val: EpollCtl) -> JournalEpollCtlV1

Converts to this type from the input type.

impl From<JournalEpollCtlV1> for EpollCtl

fn from(val: JournalEpollCtlV1) -> EpollCtl

Converts to this type from the input type.

impl FromToNativeWasmType for EpollCtl

type Native = i32

Native Wasm type.

fn to_native(self) -> <EpollCtl as FromToNativeWasmType>::Native

Convert self to Self::Native.

fn from_native(n: <EpollCtl as FromToNativeWasmType>::Native) -> EpollCtl

Convert a value of kind Self::Native to Self.

fn is_from_store(&self, _store: &impl AsStoreRef) -> bool

Returns whether the given value is from the given store.

impl Hash for EpollCtl

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for EpollCtl

fn eq(&self, other: &EpollCtl) -> 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 Serialize for EpollCtl

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<u32> for EpollCtl

type Error = TryFromPrimitiveError<EpollCtl>

fn try_from(number: u32) -> Result<EpollCtl, TryFromPrimitiveError<EpollCtl>>

Performs the conversion.

impl TryFromPrimitive for EpollCtl

const NAME: &'static str = "EpollCtl"

type Primitive = u32

fn try_from_primitive( number: <EpollCtl as TryFromPrimitive>::Primitive, ) -> Result<EpollCtl, TryFromPrimitiveError<EpollCtl>>

impl ValueType for EpollCtl

fn zero_padding_bytes(&self, _bytes: &mut [MaybeUninit<u8>])

This method is passed a byte slice which contains the byte representation of self. It must zero out any bytes which are uninitialized (e.g. padding bytes).

impl Copy for EpollCtl
