[−][src]Struct sequoia_openpgp::serialize::stream::Compressor
Compresses a packet stream.
Writes a compressed data packet containing all packets written to this writer.
Example
extern crate sequoia_openpgp as openpgp; use std::io::Write; use openpgp::serialize::stream::{Message, Compressor, LiteralWriter}; use openpgp::types::CompressionAlgorithm; let mut o = vec![]; { let message = Message::new(&mut o); let w = Compressor::new(message) .algo(CompressionAlgorithm::Uncompressed).build()?; let mut w = LiteralWriter::new(w).build()?; w.write_all(b"Hello world.")?; w.finalize()?; } assert_eq!(b"\xc8\x15\x00\xcb\x12b\x00\x00\x00\x00\x00Hello world.", o.as_slice());
Methods
impl<'a> Compressor<'a>
[src]
pub fn new(inner: Stack<'a, Cookie>) -> Self
[src]
Creates a new compressor using the given algorithm.
Passing None
to compression_level
selects the default
compression level.
pub fn algo(self, algo: CompressionAlgorithm) -> Self
[src]
Sets the compression algorithm.
pub fn level(self, level: CompressionLevel) -> Self
[src]
Sets the compression level.
pub fn build(self) -> Result<Stack<'a, Cookie>>
[src]
Finalizes the literal writer, returning the writer stack.
format
, filename
, and date
will be emitted as part of
the literal packets headers. Note that these headers will not
be authenticated by signatures (but will be authenticated by a
SEIP/MDC container), and are therefore unreliable and should
not be trusted.
