Struct VideoStreamDescriptor 

pub struct VideoStreamDescriptor {
    pub multiple_frame_rate_flag: bool,
    pub frame_rate_code: FrameRateCode,
    pub mpeg_1_only_flag: bool,
    pub constrained_parameter_flag: bool,
    pub still_picture_flag: bool,
    pub profile_and_level_indication: Option<u8>,
    pub chroma_format: Option<u8>,
    pub frame_rate_extension_flag: Option<bool>,
}

Video Stream Descriptor.

If mpeg_1_only_flag is true, profile_and_level_indication, chroma_format, and frame_rate_extension_flag are absent (body is only 1 byte instead of 3).

Fields

multiple_frame_rate_flag: bool

1 — more than one frame rate may be present (see Table 2-47 “also includes”).

frame_rate_code: FrameRateCode

Frame rate code (Table 2-47).

mpeg_1_only_flag: bool

1 — stream constrained to MPEG-1 (no profile/level/chroma fields follow).

constrained_parameter_flag: bool

Constrained parameters flag.

still_picture_flag: bool

Still picture flag.

profile_and_level_indication: Option<u8>

Profile and level indication — only when mpeg_1_only_flag is false.

chroma_format: Option<u8>

Chroma format (H.262 §6.3.11) — only when mpeg_1_only_flag is false.

frame_rate_extension_flag: Option<bool>

Frame rate extension flag — only when mpeg_1_only_flag is false.

Trait Implementations

impl Clone for VideoStreamDescriptor

fn clone(&self) -> VideoStreamDescriptor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VideoStreamDescriptor

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

Formats the value using the given formatter.

impl<'a> DescriptorDef<'a> for VideoStreamDescriptor

const TAG: u8 = TAG

Wire descriptor_tag.

const NAME: &'static str = "VIDEO_STREAM"

Diagnostic name. Convention (workspace-wide): SCREAMING_SNAKE, suffix-free — SHORT_EVENT, EXTENSION, NETWORK_NAME (no _descriptor suffix).

impl Eq for VideoStreamDescriptor

impl<'a> From<VideoStreamDescriptor> for AnyDescriptor<'a>

fn from(d: VideoStreamDescriptor) -> Self

Converts to this type from the input type.

impl<'a> Parse<'a> for VideoStreamDescriptor

type Error = Error

The error type this implementer returns. Typically the enclosing crate’s Error enum.

fn parse(bytes: &'a [u8]) -> Result<Self>

Parse bytes as Self. Returns Err(Self::Error) on any protocol violation or buffer underrun.

impl PartialEq for VideoStreamDescriptor

fn eq(&self, other: &VideoStreamDescriptor) -> 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.

impl Serialize for VideoStreamDescriptor

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Serialize for VideoStreamDescriptor

type Error = Error

The error type this implementer returns (usually the same as the corresponding Parse impl, but need not be).

fn serialized_len(&self) -> usize

Number of bytes serialize_into will write.

fn serialize_into(&self, buf: &mut [u8]) -> Result<usize>

Write the serialised form into buf. Returns the number of bytes written (always equal to serialized_len()).

fn to_bytes(&self) -> Vec<u8>

where Self::Error: Debug,

Convenience: allocate a Vec and serialise into it.

impl StructuralPartialEq for VideoStreamDescriptor

impl<'a> Yokeable<'a> for VideoStreamDescriptor

where Self: Sized,

type Output = VideoStreamDescriptor

This type MUST be Self with the 'static replaced with 'a, i.e. Self<'a>

fn transform(&self) -> &Self::Output

This method must cast self between &'a Self<'static> and &'a Self<'a>.

fn transform_owned(self) -> Self::Output

This method must cast self between Self<'static> and Self<'a>.

unsafe fn make(this: Self::Output) -> Self

This method can be used to cast away Self<'a>’s lifetime.

fn transform_mut<F>(&'a mut self, f: F)

where F: 'static + for<'b> FnOnce(&'b mut Self::Output),

This method must cast self between &'a mut Self<'static> and &'a mut Self<'a>, and pass it to f.
