Honeybadger Notifier for Rust

Honeybadger is an error-tracking service run by Honeybadger Industries LLC.

mightybadger-rs is an unofficial Honeybadger notifier for Rust, which hooks into panics and error responses, collects related information, and sends reports to the Honeybadger API server.

In addition to standalone configuration, it provides middlewares for Rocket, Gotham, and Actix Web.

Standalone

[dependencies]
mightybadger = { git = "https://github.com/qnighy/mightybadger-rs.git", rev = "da98547" }

extern crate mightybadger;

use std::fs::File;

fn main() {
    mightybadger::setup();

    match File::open("quux.quux") {
        Ok(_) => eprintln!("quux.quux exists."),
        Err(e) => mightybadger::notify(&e),
    };

    panic!("test panic");
}

With Rocket

[dependencies]
mightybadger = { git = "https://github.com/qnighy/mightybadger-rs.git", rev = "da98547" }
mightybadger-rocket = { git = "https://github.com/qnighy/mightybadger-rocket.git", rev = "da98547" }

extern crate mightybadger;
extern crate mightybadger_rocket;

...

fn main() {
    mightybadger::setup();
    rocket::ignite()
        ...
        .attach(mightybadger_rocket::HoneybadgerHook::new())
        .launch();
}

With Gotham

[dependencies]
mightybadger = { git = "https://github.com/qnighy/mightybadger-rs.git", rev = "da98547" }
mightybadger-gotham = { git = "https://github.com/qnighy/mightybadger-gotham.git", rev = "da98547" }

extern crate mightybadger;
extern crate mightybadger_gotham;

...

fn router() -> Router {
    let (chain, pipelines) = single_pipeline(
        new_pipeline()
            .add(mightybadger_gotham::HoneybadgerMiddleware)
            .build(),
    );
    build_router(chain, pipelines, |route| { ... })
}

...

fn main() {
    mightybadger::setup();
    gotham::start(..., router())
}

With Actix Web

[dependencies]
mightybadger = { git = "https://github.com/qnighy/mightybadger-rs.git", rev = "da98547" }
mightybadger-actix-web = { git = "https://github.com/qnighy/mightybadger-actix-web.git", rev = "da98547" }

extern crate mightybadger;
extern crate mightybadger_actix_web;

...

fn main() {
    mightybadger::setup();

    server::new(|| {
        App::new()
            .middleware(mightybadger_actiX_web::HoneybadgerMiddleware::new())
            ..
    }).bind(..)
        .unwrap()
        .run();
}

Configuration

It automatically reads the following environment variables at mightybadger::setup():

HONEYBADGER_API_KEY
HONEYBADGER_ENV
HONEYBADGER_REPORT_DATA
HONEYBADGER_ROOT
HONEYBADGER_REVISION
HONEYBADGER_HOSTNAME

Moreover, you can programmatically configure the Honeybadger client as follows:

fn main() {
    mightybadger::setup();
    mightybadger::configure(|config| {
        if config.api_key.is_none() {
            config.api_key = Some("abcd1234".to_string());
        }
        config.env = Some("production".to_string());
        config.report_data = Some(true);
        config.root = Some("/home/ubuntu/app".to_string());
        config.revision = Some("0123456789abcdef0123456789abcdef01234567".to_string());
        config.hostname = Some("api.example.com".to_string());
        config.request.filter_keys = Some(vec![
            "password".to_string(),
            "HTTP_AUTHORIZATION".to_string(),
            "passcode".to_string(),
        ]);
    });
}

Development Status

Note: it's still in its early stage and the Rust API is subject to change. I strongly recommend you to insert rev = ".." attribute in the dependencies to prevent breakage.
