Learning goals

• Basic rust usage
• CI/CD setup
• Containerization
• Cloud service integration
• Metrics, logs, traces
• Familiarize with rust toolchain: testing, async/await

Notes

cargo watch -x check -x test -x run to run compilation/test/run on file changes.

To check test coverage:

cargo install cargo-tarpaulin
cargo tarpaulin --ignore-tests

To disable a clippy warning: #[allow(clippy::lint_name)]

TODOs

Ch3

• Understand mod, pub use (e.g., in mod.rs).
• Understand when to use, e.g. use crate::routes vs use zero2prod::startup::run.

Ch4

• Understand all those tracing related crates (e.g., tracing::instrument).
• Wire tracing with open telemetry (tracing-opentelemetry).
• tracing v.s. log.

Ch5

• Use a container image for the app. E.g. Wolfi.
• Deploy to cloudflare if possible.

Ch6

• .into() method
• ? operator

Ch8 - Error handling

• std::fmt::Debug and std::fmt::Display.
• ? v.s. unwrap().
• async/await.
