Struct Datagrams 

pub struct Datagrams {
    pub readable_stream_reader: ReadableStreamByobReader,
    pub writable_stream_writer: WritableStreamDefaultWriter,
    pub read_buffer_size: u32,
    pub read_buffer: Mutex<Option<ArrayBuffer>>,
    pub unlock_streams_on_drop: bool,
}

Datagrams hold the portions of the session that are responsible for working with the datagrams.

Fields

readable_stream_reader: ReadableStreamByobReader

The datagram reader.

writable_stream_writer: WritableStreamDefaultWriter

The datagram writer.

read_buffer_size: u32

The desired size of the datagram read buffer. Used to allocate the datagram read buffer in case it gets lost.

read_buffer: Mutex<Option<ArrayBuffer>>

The datagram read internal buffer.

unlock_streams_on_drop: bool

Unlock the streams on drop.

Implementations

impl Datagrams

pub fn from_transport(transport: &WebTransport) -> Self

Create a datagrams state from the transport.

pub fn from_transport_datagrams( datagrams: &WebTransportDatagramDuplexStream, ) -> Self

Create a datagrams state from the transport datagrams.

impl Datagrams

pub async fn receive_with<R>( &self, max_read_size: Option<u32>, f: impl FnOnce(&mut Uint8Array) -> R, ) -> Result<R, Error>

Receive the datagram and handle the buffer with the given function.

Cloning the buffer in the f will result in the undefined behaviour, because it will create a second reference to an object that is intended to be under a mut ref. Although is would not teachnically be unsafe, it would violate the borrow checker rules.

Trait Implementations

impl Debug for Datagrams

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

Formats the value using the given formatter.

impl Drop for Datagrams

fn drop(&mut self)

Executes the destructor for this type.
