Struct Streams

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

A collection of streams. Streams implements IntoIterator to iterate over the streams.

Implementations

impl<'a> Streams<'a>

pub const unsafe fn new(input: *mut AVFormatContext) -> Self

Creates a new Streams instance.

Safety

This function is unsafe because the caller must ensure that the lifetime & the mutablity of the AVFormatContext matches the lifetime & mutability of the Streams.

pub fn best_index(&self, media_type: AVMediaType) -> Option<usize>

Returns the index of the best stream of the given media type.

pub fn best(&'a self, media_type: AVMediaType) -> Option<Const<'a, Stream<'a>>>

Returns the best stream of the given media type.

pub fn best_mut(&'a mut self, media_type: AVMediaType) -> Option<Stream<'a>>

Returns the best mutable stream of the given media type.

pub const fn iter(&'a self) -> StreamIter<'a>

Returns an iterator over the streams.

pub const fn len(&self) -> usize

Returns the length of the streams.

pub const fn is_empty(&self) -> bool

Returns whether the streams are empty.

pub const fn get(&'a mut self, index: usize) -> Option<Stream<'a>>

Returns the stream at the given index.

pub const unsafe fn get_unchecked(&self, index: usize) -> Option<Stream<'a>>

Returns the stream at the given index.

Safety

This function is unsafe because it does not require mutability. The caller must guarantee that the stream is not mutated and that multiple streams of the same index exist.

Trait Implementations

impl Debug for Streams<'_>

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

Formats the value using the given formatter.

impl<'a> IntoIterator for Streams<'a>

type IntoIter = StreamIter<'a>

Which kind of iterator are we turning this into?

type Item = Const<'a, Stream<'a>>

The type of the elements being iterated over.

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl Send for Streams<'_>

Safety: Streams is safe to send between threads.
