Struct sctp_proto::Stream

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

Stream represents an SCTP stream

Implementations

impl<'a> Stream<'a>

pub fn read(&mut self) -> Result<Option<Chunks>, Error>

read reads a packet of len(p) bytes, dropping the Payload Protocol Identifier. Returns EOF when the stream is reset or an error if the stream is closed otherwise.

pub fn read_sctp(&mut self) -> Result<Option<Chunks>, Error>

read_sctp reads a packet of len(p) bytes and returns the associated Payload Protocol Identifier. Returns EOF when the stream is reset or an error if the stream is closed otherwise.

pub fn write_sctp( &mut self, p: &Bytes, ppi: PayloadProtocolIdentifier ) -> Result<usize, Error>

write_sctp writes len(p) bytes from p to the DTLS connection

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

Send data on the given stream.

Uses the deafult payload protocol (PPI).

Returns the number of bytes successfully written.

pub fn write_with_ppi( &mut self, data: &[u8], ppi: PayloadProtocolIdentifier ) -> Result<usize, Error>

Send data on the given stream, with a specific payload protocol.

Returns the number of bytes successfully written.

pub fn write_chunk(&mut self, p: &Bytes) -> Result<usize, Error>

write writes len(p) bytes from p with the default Payload Protocol Identifier

pub fn write_chunks(&mut self, data: &mut [Bytes]) -> Result<usize, Error>

Send data on the given stream

Returns the number of bytes and chunks successfully written. Note that this method might also write a partial chunk. In this case it will not count this chunk as fully written. However the chunk will be advanced and contain only non-written data after the call.

pub fn is_readable(&self) -> bool

pub fn is_writable(&self) -> bool

pub fn stop(&mut self) -> Result<(), Error>

stop closes the read-direction of the stream. Future calls to read are not permitted after calling stop.

pub fn finish(&mut self) -> Result<(), Error>

finish closes the write-direction of the stream. Future calls to write are not permitted after calling Close.

pub fn stream_identifier(&self) -> StreamId

stream_identifier returns the Stream identifier associated to the stream.

pub fn set_default_payload_type( &mut self, default_payload_type: PayloadProtocolIdentifier ) -> Result<(), Error>

set_default_payload_type sets the default payload type used by write.

pub fn get_default_payload_type( &self ) -> Result<PayloadProtocolIdentifier, Error>

get_default_payload_type returns the payload type associated to the stream.

pub fn set_reliability_params( &mut self, unordered: bool, rel_type: ReliabilityType, rel_val: u32 ) -> Result<(), Error>

set_reliability_params sets reliability parameters for this stream.

pub fn buffered_amount(&self) -> Result<usize, Error>

buffered_amount returns the number of bytes of data currently queued to be sent over this stream.

pub fn buffered_amount_low_threshold(&self) -> Result<usize, Error>

buffered_amount_low_threshold returns the number of bytes of buffered outgoing data that is considered “low.” Defaults to 0.

pub fn set_buffered_amount_low_threshold( &mut self, th: usize ) -> Result<(), Error>

set_buffered_amount_low_threshold is used to update the threshold. See buffered_amount_low_threshold().
