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

An optional FIDL vector

Implementations

impl<'buf, T> WireOptionalVector<'buf, 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 take(&mut self) -> Option<WireVector<'buf, T>>

Takes the vector out of the option, if any.

pub fn as_ref(&self) -> Option<&WireVector<'buf, T>>

Gets a reference to the vector, if any.

pub fn as_mut(&mut self) -> Option<&mut WireVector<'buf, T>>

Gets a mutable reference to the vector, if any.
