Struct WireOptionalVector

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

An optional FIDL vector

Implementations

impl<T> WireOptionalVector<T>

pub fn encode_present(slot: Slot<'_, Self>, len: u64)

Encodes that a vector is present in a slot.

pub fn encode_absent(slot: Slot<'_, Self>)

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<'_, Self>, 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> Debug for WireOptionalVector<T>

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

Formats the value using the given formatter.

impl<D: Decoder + ?Sized, T: Decode<D>> Decode<D> for WireOptionalVector<T>

fn decode(slot: Slot<'_, Self>, 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: TakeFrom<WT>, WT> TakeFrom<WireOptionalVector<WT>> for Option<Vec<T>>

fn take_from(from: &WireOptionalVector<WT>) -> Self

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.

impl<T> ZeroPadding for WireOptionalVector<T>

unsafe fn zero_padding(ptr: *mut Self)

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