Bootstrap client binder

Fields

remote_pubkey: PublicKey

duplex: Limiter<TcpStream>

prev_message: Option<Hash>

version_serializer: VersionSerializer

cfg: BootstrapClientConfig

Implementations

impl BootstrapClientBinder

pub fn new( duplex: TcpStream, remote_pubkey: PublicKey, cfg: BootstrapClientConfig, limit: Option<u64>, ) -> Self

Creates a new WriteBinder.

Argument

• duplex: duplex stream.
• limit: limit max bytes per second (up and down)

pub fn handshake(&mut self, version: Version) -> Result<(), BootstrapError>

Performs a handshake. Should be called after connection NOT cancel-safe

pub fn next_timeout( &mut self, duration: Option<Duration>, ) -> Result<BootstrapServerMessage, BootstrapError>

Reads the next message.

pub fn send_timeout( &mut self, msg: &BootstrapClientMessage, duration: Option<Duration>, ) -> Result<(), BootstrapError>

Send a message to the bootstrap server

fn decode_msg_leader( &self, leader_buff: &[u8; 69], ) -> Result<ServerMessageLeader, BootstrapError>

We are using this instead of of our library deserializer as the process is relatively straight forward and makes error-type management cleaner

Trait Implementations

impl BindingReadExact for BootstrapClientBinder

fn set_read_timeout(&mut self, duration: Option<Duration>) -> Result<(), Error>

Internal helper

fn read_exact_timeout( &mut self, buf: &mut [u8], deadline: Option<Instant>, ) -> Result<(), (Error, usize)>

similar to std::io::Read::read_exact, but with a timeout that is function-global instead of per-individual-read

impl BindingWriteExact for BootstrapClientBinder

fn set_write_timeout(&mut self, duration: Option<Duration>) -> Result<(), Error>

Internal helper

fn write_all_timeout( &mut self, write_buf: &[u8], deadline: Option<Instant>, ) -> Result<(), (Error, usize)>

impl Read for BootstrapClientBinder

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

Pull some bytes from this source into the specified buffer, returning how many bytes were read.

fn read_vectored(&mut self, bufs: &mut [IoSliceMut<'_>]) -> Result<usize, Error>

Like read, except that it reads into a slice of buffers.

fn is_read_vectored(&self) -> bool

🔬This is a nightly-only experimental API. (can_vector)

Determines if this Reader has an efficient read_vectored implementation.

fn read_to_end(&mut self, buf: &mut Vec<u8>) -> Result<usize, Error>

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

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

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

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

Read the exact number of bytes required to fill buf.

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

🔬This is a nightly-only experimental API. (read_buf)

Pull some bytes from this source into the specified buffer.

fn read_buf_exact(&mut self, cursor: BorrowedCursor<'_>) -> Result<(), Error>

🔬This is a nightly-only experimental API. (read_buf)

Read the exact number of bytes required to fill cursor.

fn by_ref(&mut self) -> &mut Self

where Self: Sized,

Creates a “by reference” adaptor for this instance of Read.

fn bytes(self) -> Bytes<Self>

where Self: Sized,

Transforms this Read instance to an Iterator over its bytes.

fn chain<R>(self, next: R) -> Chain<Self, R>

where R: Read, Self: Sized,

Creates an adapter which will chain this stream with another.

fn take(self, limit: u64) -> Take<Self>

where Self: Sized,

Creates an adapter which will read at most limit bytes from it.

impl Write for BootstrapClientBinder

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

Write a buffer into this writer, returning how many bytes were written.

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

Flush this output stream, ensuring that all intermediately buffered contents reach their destination.

fn write_vectored(&mut self, bufs: &[IoSlice<'_>]) -> Result<usize, Error>

Like write, except that it writes from a slice of buffers.

fn is_write_vectored(&self) -> bool

🔬This is a nightly-only experimental API. (can_vector)

Determines if this Writer has an efficient write_vectored implementation.

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

Attempts to write an entire buffer into this writer.

fn write_all_vectored(&mut self, bufs: &mut [IoSlice<'_>]) -> Result<(), Error>

🔬This is a nightly-only experimental API. (write_all_vectored)

Attempts to write multiple buffers into this writer.

fn write_fmt(&mut self, fmt: Arguments<'_>) -> Result<(), Error>

Writes a formatted string into this writer, returning any error encountered.

fn by_ref(&mut self) -> &mut Self

where Self: Sized,

Creates a “by reference” adapter for this instance of Write.
