The language itself: ownership, lifetimes, error handling, Serde and the idioms that make the borrow checker feel like help.
A practical threat model for Rust code: what the compiler prevents, what it does not, and the checklist of supply chain, input handling, secrets, cryptography and deployment risks.
A package has a Cargo.toml, a crate is one compilation unit, and a module is a namespace inside it. Learn how the three nest and what each one changes.
A guide to testing Rust code: unit tests beside the code, integration tests in tests, doc tests, property tests, snapshots, mocks, async tests and the commands to run them.
Modules organize Rust code and control what is public. Learn mod, pub, use, super, self, file layout and why privacy is by module and not by type.
A guide to taking a Rust service from cargo build to production: release profile, CI, containers, configuration, secrets, health checks, observability and safe rollouts.
Define a struct, give it methods in an impl block, add associated functions like new, and see tuple and unit structs plus update syntax and derive.
Option replaces null in Rust. Learn Some and None, map, and_then, unwrap_or, the question mark operator and why unwrap on None panics.
rustup installs and switches Rust toolchains, targets and components. A guide to channels, overrides, rust-toolchain.toml, cross targets, offline use and clean upgrades.
Rust enums carry data in each variant, which replaces the class hierarchy and the nullable field. See the syntax, match, methods, and where it beats inheritance.
Rust match is exhaustive: the compiler checks every case. Learn literals, ranges, guards, bindings, tuple, struct and slice patterns with working examples.
A guide to SQLx: async queries without an ORM, compile-time checked SQL, pools, migrations, transactions and the choices around them.
A guide to embedded Rust from the first blinking LED to firmware structure: no_std, the HAL traits, runtimes, flashing, debugging and size.
