Struct Counter 

pub struct Counter { /* private fields */ }

A Zircon Counter.

Implementations

impl Counter

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

Encodes a Counter as present in an output.

pub fn is_invalid(&self) -> bool

Returns whether the underlying zx_handle_t is invalid.

pub fn as_raw_handle(&self) -> zx_handle_t

Returns the underlying [zx_handle_t].

Trait Implementations

impl Constrained for Counter

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 Counter

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

Formats the value using the given formatter.

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

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> Encode<Counter, E> for Counter

fn encode( self, encoder: &mut E, out: &mut MaybeUninit<Counter>, constraint: <Counter as Constrained>::Constraint, ) -> Result<(), EncodeError>

Encodes this value into an encoder and output.

const COPY_OPTIMIZATION: CopyOptimization<Self, W> = _

Whether the conversion from Self to W is equivalent to copying the raw bytes of Self.

impl FromWire<Counter> for Counter

fn from_wire(wire: Counter) -> Self

Converts the given owned value to this type.

const COPY_OPTIMIZATION: CopyOptimization<W, Self> = _

Whether the conversion from W to Self is equivalent to copying the raw bytes of W.

impl IntoNatural for Counter

type Natural = Counter

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 Counter

type Narrowed<'de> = Counter

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.
