Rust Programming Course: From Beginner to Expert 2.0

Explore rust for loop syntaxes using ranges, exclusive and inclusive ends, and step_by for custom increments; use reverse for descending orders and destructuring for vectors of tuples.

Master comments, the print macro, and escape sequences to write clearer, well-structured Rust code, using positional and named arguments, quotes handling, and backslash tricks.

Explore rust compiler directives as annotations that guide the compiler on parsing code, applicable to variables, functions, or whole files, including the allow directive to suppress unused warnings.

Learn how associativity directs evaluation in Rust, with left associative arithmetic and right associative assignment. Discover why explicit boolean conditions and operator overloading via traits matter.

Explore rust ownership rules, including move on assignment, single owner concept, and drop on scope exit, plus clone for deep copies and stack-heap memory layout.

Explore how ownership moves through Rust functions, including take ownership, give ownership, and take-and-return patterns for heap-allocated vectors. See stack data is copied, and when cloning or references are used.

Master the basics of structs, including named field, tuple, and unit-like structs, learning to define, initialize, and access fields with dot notation while managing ownership and mutability.

Extend structs with implementation blocks to add behavior. Use self forms (immutable, mutable, and owned), plus dot notation and new as an associated function.

Explore rust's result enum for explicit error handling by improving a student database example; learn to replace option with result, use ok and error variants, and handle failures with match.

Master Rust method chaining constraints by examining how owned, mutable, and immutable self shape chainability. The lesson uses a bank account example to illustrate constructors, deposits, withdrawals, and owner changes.

Discover how Rust pattern matching destructures struct fields to access only the needed data. Learn about bindings in match arms and function parameters, including concrete values and ignored fields.

Explore how Rust modules organize code into product, customer, and order units, control visibility with pub, and use absolute or relative paths and use declarations to simplify scope.

Explore how cargo test generates and filters test reports for binary and library crates, view outputs, and manage ignored tests and patterns to focus on relevant tests.

Explore integration tests that verify how library components work together through the public interface. Store tests in the top-level tests directory, with each file compiling as a separate crate.

Benchmark the performance of two sorting implementations to see if changes speed up processing time, using the criterion crate, cargo bench, and the benches directory.

Explore static vs dynamic dispatch in Rust, learn how monomorphization creates specialized code, and use trait objects behind pointers like Box and dyn to enable flexible return types.

Learn how to use closures in Rust to validate users, store validator logic, and handle environment capture with Fn, FnMut, and FnOnce traits.

Explore the Rust iterator design pattern by implementing the iterator trait for an employee records collection, using an associated item type and the mandatory next method to yield items.
