Master formatting specifiers, debug printing, and statement structures in Rust.

Understand immutable by default variables, the mut keyword, and shadowing.

Master Rust primitives: signed/unsigned ints, floats, booleans, tuples, and fixed arrays.

Write modular functions and understand statements vs. expressions in Rust.

Branch execution with if, else if, else, and assign values directly from if expressions.

Master Rust’s core memory safety paradigm: single owner, moves, and automatic drop.

Share access to data without transferring ownership using immutable references.

Modify borrowed data and understand Rust’s compile-time data race prevention rule.

Understand string slices (&str), owned String buffers, and contiguous array slices.

Iterate with loop expressions, returning values from loops, while, and for..in ranges.

Harness exhaustive pattern matching, guard clauses, and the wildcard operator.

Define custom domain models with structs and encapsulate behavior using impl blocks.

Model multi-variant states and eliminate null pointer bugs with Option<T>.

Write clean single-pattern matches and early return guard clauses.

Store dynamically-sized sequences on the heap with Vec<T> and vec! macro.

Handle recoverable errors gracefully using Result and the ergonomic ? operator.

Define abstract interfaces with traits and write reusable generic functions.

Transform collections with anonymous closures (|x| ...) and composable iterator adaptors.
