Implementations

impl SequenceHeaderObu

pub const fn header(&self) -> &ObuHeader

Returns a reference to the header of the OBU.

pub fn parse(header: ObuHeader, reader: &mut impl Read) -> Result<Self>

Parses the sequence header from the given reader.

The given header will be part of the returned struct and can be accessed through the SequenceHeaderObu::header function.

Trait Implementations

impl Clone for SequenceHeaderObu

fn clone(&self) -> SequenceHeaderObu

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SequenceHeaderObu

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

Formats the value using the given formatter.

impl PartialEq for SequenceHeaderObu

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