Trait Implementations

impl Clone for Vp9Packet

fn clone(&self) -> Vp9Packet

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Vp9Packet

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

Formats the value using the given formatter.

impl Default for Vp9Packet

fn default() -> Vp9Packet

Returns the “default value” for a type.

impl Depacketizer for Vp9Packet

fn depacketize(&mut self, packet: &Bytes) -> Result<Bytes>

depacketize parses the passed byte slice and stores the result in the Vp9Packet this method is called upon

fn is_partition_head(&self, payload: &Bytes) -> bool

is_partition_head checks whether if this is a head of the VP9 partition

fn is_partition_tail(&self, marker: bool, _payload: &Bytes) -> bool

Checks if the packet is at the end of a partition. This should return false if the result could not be determined.

impl PartialEq for Vp9Packet

fn eq(&self, other: &Vp9Packet) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
