actix-webactix-web
The sentry-actix crate adds a middleware for actix-web that captures errors and report them to Sentry.
To use this middleware, configure Sentry then add it to your actix web app as a middleware. Because actix is generally working with non sendable objects and is highly concurrent, this middleware creates a new hub per request. As a result, many of the Sentry integrations, such as breadcrumbs, do not work unless you bind the actix hub.
Note: Macros like #[tokio::main] and #[actix_web::main] are not supported. The Sentry client must be initialized before the async runtime is started so that all threads are correctly connected to the Hub.
In your Cargo.toml:
Cargo.toml[dependencies]
actix-web = "4.3.1"
sentry = "0.32.3"
sentry-actix = "0.32.3"
And your Rust code:
main.rsuse std::io;
use actix_web::{get, App, Error, HttpRequest, HttpServer};
#[get("/")]
async fn failing(_req: HttpRequest) -> Result<String, Error> {
Err(io::Error::new(io::ErrorKind::Other, "An error happens here").into())
}
fn main() -> io::Result<()> {
let _guard = sentry::init((
"https://examplePublicKey@o0.ingest.sentry.io/0",
sentry::ClientOptions {
release: sentry::release_name!(),
..Default::default()
},
));
std::env::set_var("RUST_BACKTRACE", "1");
actix_web::rt::System::new().block_on(async {
HttpServer::new(|| {
App::new()
.wrap(sentry_actix::Sentry::new())
.service(failing)
})
.bind("127.0.0.1:3001")?
.run()
.await
})?;
Ok(())
}
When using the actix integration, a new per-request Hub will be created from the main Hub, and will be set automatically as the current Hub (Hub::current()). No manual intervention in needed.
