Trait FifoWritable

pub trait FifoWritable<W: FifoEntry>
where
    Self: Sized,
{
    // Required method
    fn write<B: ?Sized + FifoWriteBuffer<W>>(
        &self,
        cx: &mut Context<'_>,
        entries: &B,
    ) -> Poll<Result<usize, Status>>;

    // Provided method
    fn write_entries<'a, B: ?Sized + FifoWriteBuffer<W>>(
        &'a self,
        entries: &'a B,
    ) -> WriteEntries<'a, Self, B, W>  { ... }
}

Identifies that the object may be used to write entries into a FIFO.

Required Methods

fn write<B: ?Sized + FifoWriteBuffer<W>>( &self, cx: &mut Context<'_>, entries: &B, ) -> Poll<Result<usize, Status>>

Writes entries to the fifo and registers this Fifo as needing a write on receiving a zx::Status::SHOULD_WAIT.

Returns the number of elements processed.

Provided Methods

fn write_entries<'a, B: ?Sized + FifoWriteBuffer<W>>( &'a self, entries: &'a B, ) -> WriteEntries<'a, Self, B, W>

Creates a future that transmits entries to be written.

The returned future will return after an entry has been received on this fifo. The future will resolve to the fifo once all elements have been transmitted.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
