Struct sequoia_openpgp::serialize::stream::ArbitraryWriter[][src]

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

Writes an arbitrary packet.

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

Implementations

Creates a new writer with the given tag.

Examples
use std::io::Write;
use sequoia_openpgp as openpgp;
use openpgp::packet::Tag;
use openpgp::serialize::stream::{Message, ArbitraryWriter};

let mut sink = vec![];
{
    let message = Message::new(&mut sink);
    let mut message = ArbitraryWriter::new(message, Tag::Literal)?;
    message.write_all(b"t")?;                   // type
    message.write_all(b"\x00")?;                // filename length
    message.write_all(b"\x00\x00\x00\x00")?;    // date
    message.write_all(b"Hello world.")?;        // body
    message.finalize()?;
}
assert_eq!(b"\xcb\x12t\x00\x00\x00\x00\x00Hello world.",
           sink.as_slice());
