Using highlight.io without a framework in Rust

Learn how to set up highlight.io without a framework.

1

Install the Highlight Rust SDK.

Add Highlight to your Config.toml. You'll need to pick your features based on what kind of runtime your project uses. If everything is synchronous, you can use the default features. If you're using tokio, turn off default features and use the feature tokio. If you're using async-std, turn off default features and use the feature async-std.

[dependencies.highlightio] version = "1" default-features = ... features = [...]

2

Initialize the Highlight Rust SDK.

highlightio::Highlight::init initializes the SDK.

use highlightio::{Highlight, HighlightConfig}; // or async fn main() // with #[tokio::main] if you're using tokio, etc. fn main() { let h = Highlight::init(HighlightConfig { project_id: "<YOUR_PROJECT_ID>".to_string(), service_name: "my-rust-app".to_string(), service_version: "git-sha".to_string(), ..Default::default() }).expect("Failed to initialize Highlight.io"); // ... h.shutdown(); }

3

Capture errors.

Highlight::capture_error can be used to explicitly capture any error.

fn do_something() -> Result<(), Error> { // ... } fn main() { // ... match do_something() { Ok(_) => {}, Err(e) => h.capture_error(&e), }; }

4

Verify your errors are being recorded.

Now that you've set up the SDK, you can verify that the backend error handling works by sending an error in. Visit the highlight errors page and check that backend errors are coming in.

fn main() { // ... let e = std::io::Error::new( std::io::ErrorKind::Other, "This is a test error." ); h.capture_error(&e); }

5

Set up logging.

Start sending logs to Highlight! Follow the logging setup guide to get started.
