logfmt formatter for slog

This is a pretty straightforward logfmt formatter with a customizable prefix. The formatter exposed by the crate is not Send or Sync, so you'll have to wrap it in slog-async or similar.

lib.rs:

slog_logfmt - a logfmt formatter for slog.

This crate exposes a slog drain that formats messages as logfmt.

Example

use slog_logfmt::Logfmt;
use slog::{debug, o, Drain, Logger};
use std::io::stdout;

let drain = Logfmt::new(stdout()).build().fuse();
let drain = slog_async::Async::new(drain).build().fuse();
let logger = Logger::root(drain, o!("logger" => "tests"));
debug!(logger, #"tag", "hi there"; "foo" => "bar'baz\"");

Writes:

DEBG | #tag	hi there	logger="tests" foo="bar\'baz\""
