Struct WireOptionalVector

pub struct WireOptionalVector<T> { /* private fields */ }

An optional FIDL vector

Implementations

impl<T> WireOptionalVector<T>

pub fn encode_present(slot: Slot<'_, WireOptionalVector<T>>, len: u64)

Encodes that a vector is present in a slot.

pub fn encode_absent(slot: Slot<'_, WireOptionalVector<T>>)

Encodes that a vector is absent in a slot.

pub fn is_some(&self) -> bool

Returns whether the vector is present.

pub fn is_none(&self) -> bool

Returns whether the vector is absent.

pub fn as_ref(&self) -> Option<&WireVector<T>>

Gets a reference to the vector, if any.

pub unsafe fn decode_raw<D>( slot: Slot<'_, WireOptionalVector<T>>, decoder: &mut D, ) -> Result<(), DecodeError>

where D: Decoder + ?Sized, T: Decode<D>,

Decodes a wire vector which contains raw data.

Safety

The elements of the wire vecot rmust not need to be individually decoded, and must always be valid.

Trait Implementations

impl<T> Debug for WireOptionalVector<T>

where T: Debug,

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

Formats the value using the given formatter.

impl<D, T> Decode<D> for WireOptionalVector<T>

where D: Decoder + ?Sized, T: Decode<D>,

fn decode( slot: Slot<'_, WireOptionalVector<T>>, decoder: &mut D, ) -> Result<(), DecodeError>

Decodes a value into a slot using a decoder.

impl<T> Drop for WireOptionalVector<T>

fn drop(&mut self)

Executes the destructor for this type.

impl<T, WT> TakeFrom<WireOptionalVector<WT>> for Option<Vec<T>>

where T: TakeFrom<WT>,

fn take_from(from: &WireOptionalVector<WT>) -> Option<Vec<T>>

Converts from the given T, taking any resources that can’t be cloned.

const COPY_OPTIMIZATION: CopyOptimization<Self> = _

An optimization flag that allows the bytes of this type to be copied directly during conversion instead of calling take_from.
