Implementations

impl OptionalDebugLog

pub fn set_encoded_present(out: &mut MaybeUninit<Self>)

Encodes a DebugLog as present in an output.

pub fn set_encoded_absent(out: &mut MaybeUninit<Self>)

Encodes a DebugLog as absent in an output.

pub fn is_some(&self) -> bool

Returns whether a DebugLog is present.

pub fn is_none(&self) -> bool

Returns whether a DebugLog is absent.

pub fn as_raw_handle(&self) -> Option<zx_handle_t>

Returns the underlying [zx_handle_t], if any.

Trait Implementations

impl Constrained for OptionalDebugLog

type Constraint = ()

Type of constraint information for this type.

fn validate( _: Slot<'_, Self>, _: Self::Constraint, ) -> Result<(), ValidationError>

Validate a slot of this type against a constraint. Can be called when pointers/envelopes are just presence markers.

impl Debug for OptionalDebugLog

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

Formats the value using the given formatter.

impl<D: HandleDecoder + ?Sized> Decode<D> for OptionalDebugLog

fn decode( slot: Slot<'_, Self>, decoder: &mut D, constraint: Self::Constraint, ) -> Result<(), DecodeError>

Decodes a value into a slot using a decoder.

impl<E: HandleEncoder + ?Sized> EncodeOption<OptionalDebugLog, E> for DebugLog

fn encode_option( this: Option<Self>, encoder: &mut E, out: &mut MaybeUninit<OptionalDebugLog>, constraint: (), ) -> Result<(), EncodeError>

Encodes this optional value into an encoder and output.

impl FromWireOption<OptionalDebugLog> for DebugLog

fn from_wire_option(wire: OptionalDebugLog) -> Option<Self>

Converts the given owned value to an option of this type.

impl IntoNatural for OptionalDebugLog

type Natural = Option<DebugLog>

A good default type for this wire type to convert into.

fn into_natural(self) -> Self::Natural

Converts this type into its natural equivalent.

impl Wire for OptionalDebugLog

type Narrowed<'de> = OptionalDebugLog

The narrowed wire type, restricted to the 'de lifetime.

fn zero_padding(out: &mut MaybeUninit<Self>)

Writes zeroes to the padding for this type, if any.
