Struct Datagram 

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

An HTTP3 datagram.

Implementations

impl<'a> Datagram<'a>

pub fn new(qstream_id: QStreamId, payload: &'a [u8]) -> Self

Creates a new Datagram with a given payload.

pub fn read(quic_datagram: &'a [u8]) -> Result<Self, ErrorCode>

Reads Datagram from a QUIC datagram.

pub fn write(&self, buffer: &mut [u8]) -> Result<usize, EndOfBuffer>

Writes a Datagram as QUIC datagram into buffer.

It returns the number of bytes written. It returns Err if the buffer does not have enough capacity. See Self::write_size.

In case of Err, buffer is not written.

pub fn write_size(&self) -> usize

Returns the needed capacity to write this datagram into a buffer.

pub fn header_size(qstream_id: QStreamId) -> usize

Returns the HTTP3 header.

Computes the space overhead (HTTP3 header) due to the qstream_id encoding into an HTTP3 datagram.

pub fn qstream_id(&self) -> QStreamId

Returns the associated QStreamId.

pub fn payload(&self) -> &[u8]

Returns the payload.
