Struct Writer

pub struct Writer { /* private fields */ }

Write interface for the builder’s internal buffer. Can be used to turn header parts into bytes.

Examples

use rama_haproxy::protocol::v2::{Addresses, Writer, WriteToHeader};
use std::net::SocketAddr;

let addresses: Addresses = ("127.0.0.1:80".parse::<SocketAddr>().unwrap(), "192.168.1.1:443".parse::<SocketAddr>().unwrap()).into();
let mut writer = Writer::default();

addresses.write_to(&mut writer).unwrap();

assert_eq!(addresses.to_bytes().unwrap(), writer.finish());

Implementations

impl Writer

pub fn finish(self) -> Vec<u8>

Consumes this Writer and returns the buffer holding the proxy protocol header payloads. The returned bytes are not guaranteed to be a valid proxy protocol header.

Trait Implementations

impl Debug for Writer

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

Formats the value using the given formatter.

impl Default for Writer

fn default() -> Writer

Returns the “default value” for a type.

impl From<Vec<u8>> for Writer

fn from(bytes: Vec<u8>) -> Self

Converts to this type from the input type.

impl Write for Writer

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

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

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

Flushes 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.
