Fields

channel_type: ChannelType

The reliability and ordering guarantees requested for the channel.

priority: u16

The channel’s relative priority, one of the CHANNEL_PRIORITY_* constants.

reliability_parameter: u32

The retransmission count or message lifetime in milliseconds, interpreted according to Self::channel_type.

label: Vec<u8>

The channel label, as UTF-8 bytes.

protocol: Vec<u8>

The subprotocol name, as UTF-8 bytes. Empty if none was negotiated.

Trait Implementations

impl Clone for DataChannelOpen

fn clone(&self) -> DataChannelOpen

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DataChannelOpen

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

Formats the value using the given formatter.

impl Eq for DataChannelOpen

impl Marshal for DataChannelOpen

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

Encodes into buf, returning the number of bytes written.

fn marshal(&self) -> Result<BytesMut, Error>

Encodes into a freshly allocated buffer sized by MarshalSize::marshal_size.

impl MarshalSize for DataChannelOpen

fn marshal_size(&self) -> usize

The number of bytes Marshal::marshal_to will write for this value.

impl PartialEq for DataChannelOpen

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

Equality operator ==.

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

Inequality operator !=.

impl StructuralPartialEq for DataChannelOpen

impl Unmarshal for DataChannelOpen

fn unmarshal<B>(buf: &mut B) -> Result<Self>

where B: Buf,

Decodes one value from buf, advancing it past the bytes consumed.
