rust-systemd

Only has bindings for the journal and daemon APIs at the moment.

journal

Journal sending is supported, and systemd::journal::Journal is a (low functionality) wrapper around the read API.

HOWTO log to journald:

# cat >Cargo.toml <<EOF
[dependencies.systemd]
git = "https://github.com/jmesmon/rust-systemd"
EOF

# editor src/main.rs


#![feature(phase)]
#[phase(plugin,link)] extern crate log;
#[phase(plugin,link)] extern crate systemd;
use systemd::journal;

fn main() {
   use systemd::journal;
   use log::set_logger;
   journal::print(1, format!("Rust can talk to the journal: {}",
                             4i).as_slice());
   journal::send(["CODE_FILE=HI", "CODE_LINE=1213", "CODE_FUNCTION=LIES"]);
   set_logger(box journal::JournalLogger);
   log!(0, "HI");
   sd_journal_log!(4, "HI {}", 2i);
}

daemon

The daemon API mostly offers tools for working with raw filehandles passed to the process by systemd on socket activation. Since raw filehandles are not well supported in Rust, it's likely these functions will mostly be helpful in managing program flow; actual socket code will have to use the libc crate.

TODO

  • rustdoc
  • other systemd apis
  • split out the -sys package
