Struct WireOptionalVector

pub struct WireOptionalVector<'de, T> { /* private fields */ }

An optional FIDL vector

Implementations

impl<'de, T> WireOptionalVector<'de, T>

pub fn encode_present( out: &mut MaybeUninit<WireOptionalVector<'de, T>>, len: u64, )

Encodes that a vector is present in a slot.

pub fn encode_absent(out: &mut MaybeUninit<WireOptionalVector<'de, 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 fn to_option(self) -> Option<WireVector<'de, T>>

Converts the optional wire vector to an Option<WireVector>.

pub unsafe fn decode_raw<D>( slot: Slot<'_, WireOptionalVector<'de, 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 vector must not need to be individually decoded, and must always be valid.
