Struct SctpStream 

pub struct SctpStream(/* private fields */);

One-to-one SCTP connected stream which behaves like a TCP stream. A SctpStream can be obtained either actively by connecting to a SCTP endpoint with the connect constructor, or passively from a SctpListener which accepts new connections

Implementations

impl SctpStream

pub fn connect<A: ToSocketAddrs>(address: A) -> Result<SctpStream>

Create a new stream by connecting it to a remote endpoint

Reads all bytes until EOF in this source, placing them into buf.

fn read_to_string(&mut self, buf: &mut String) -> Result<usize, Error>

Reads all bytes until EOF in this source, appending them to buf.

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

Reads the exact number of bytes required to fill buf.

fn read_buf(&mut self, buf: BorrowedCursor<'_, u8>) -> Result<(), Error>
