rust-sentry_rocket

Sentry.io client extension for the Rocket webserver.

Instructions

Use the sentry_rocket::Error type as return error type for your handler functions (ex: Result<String, custom_derive::Error>)

Don't forget to run the running the usual let _guard = sentry::init(...); and it will send any error to sentry. (Panics on 1st error if not done)

Note that you should use the failure crate to propagate your errors if you wish to have proper backtrace handling.

Also, using sentry_rocket::sentry instead of sentry will ensure the versions match so that the initialized sentry module is the same as the one the module uses (panics on 1st error otherwise) (if doing so, you don't need sentry as a dependency for your project, only sentry_rocket).

Example

#![feature(proc_macro_hygiene, decl_macro)]

#[macro_use]
extern crate rocket;

use sentry_rocket::sentry;

#[get("/")]
fn index() -> &'static str {
	"Hello, world!"
}

#[get("/fail")]
fn fail() -> Result<(), sentry_rocket::Error> {
	something_that_may_fail()?;
	Ok(())
}

fn something_that_may_fail() -> Result<(), failure::Error> {
	let some_result = Err(std::io::Error::new(
		std::io::ErrorKind::Other,
		"Something failed",
	));
	Ok(some_result?)
}

fn main() {
	let _guard = sentry::init("https://a94ae32be2584e0bbd7a4cbb95971fee@sentry.io/1041156");
	std::env::set_var("RUST_BACKTRACE", "1");
	sentry::integrations::panic::register_panic_handler();

	rocket::ignite().mount("/", routes![index, fail]).launch();
}
