Struct SampleStream 

pub struct SampleStream<'a> { /* private fields */ }

A Stream of captured sample buffers.

Yields CMSampleBuffers and ends (None) when the stream closes. Returned by AsyncSCStream::frames; it borrows the stream and is Unpin, so it plugs straight into the futures::StreamExt combinators:

use futures_util::StreamExt;
let first_ten: Vec<_> = stream.frames().take(10).collect().await;

Trait Implementations

impl Debug for SampleStream<'_>

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

Formats the value using the given formatter.

impl Drop for SampleStream<'_>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl Stream for SampleStream<'_>

type Item = CMSampleBuffer

Values yielded by the stream.

fn poll_next( self: Pin<&mut Self>, cx: &mut Context<'_>, ) -> Poll<Option<Self::Item>>

Attempt to pull out the next value of this stream, registering the current task for wakeup if the value is not yet available, and returning None if the stream is exhausted.

fn size_hint(&self) -> (usize, Option<usize>)

Returns the bounds on the remaining length of the stream.
