Struct sequoia_openpgp::serialize::stream::ArbitraryWriter

pub struct ArbitraryWriter<'a> { /* fields omitted */ }

Writes an arbitrary packet.

This writer can be used to construct arbitrary OpenPGP packets. The body will be written using partial length encoding, or, if the body is short, using full length encoding.

Example

extern crate sequoia_openpgp as openpgp;
use std::io::Write;
use openpgp::packet::Tag;
use openpgp::serialize::stream::{Message, ArbitraryWriter};
let mut o = vec![];
{
    let mut w = ArbitraryWriter::new(Message::new(&mut o), Tag::Literal)?;
    w.write_all(b"t")?;                   // type
    w.write_all(b"\x00")?;                // filename length
    w.write_all(b"\x00\x00\x00\x00")?;    // date
    w.write_all(b"Hello world.")?;        // body
}
assert_eq!(b"\xcb\x12t\x00\x00\x00\x00\x00Hello world.", o.as_slice());

Methods

impl<'a> ArbitraryWriter<'a>

pub fn new(inner: Stack<'a, Cookie>, tag: Tag) -> Result<Stack<'a, Cookie>>

Creates a new writer with the given tag.

Trait Implementations

impl<'a> Debug for ArbitraryWriter<'a>

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

Formats the value using the given formatter.

impl<'a> Write for ArbitraryWriter<'a>

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

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

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

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

Attempts to write an entire buffer 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

Creates a "by reference" adaptor for this instance of Write.
