Rust
These concepts cover essential Rust features and techniques needed for building more complex applications. They are necessary for writing efficient, maintainable, and robust Rust code in intermediate-level projects.
-
Advanced Ownership and Borrowing
-
Dive deeper into ownership and borrowing rules, including lifetimes and the use of multiple borrows.
-
Understand how to use lifetimes to manage references and ensure memory safety across function boundaries.
-
Reason: Advanced ownership and borrowing techniques are crucial for building complex, safe Rust applications.
-
Example Task: Implement a function that returns a reference to the longest string from a list, using lifetimes.
-
-
Traits and Generics
-
Learn to define and implement traits to specify shared behaviour across different types.
-
Explore the use of generics to write flexible and reusable code that can operate on multiple types.
-
Reason: Traits and generics are key to Rust’s expressive type system, enabling polymorphism and code reuse.
-
Example Task: Create a generic function that finds the largest element in any list of items that implement the PartialOrd trait.
-
-
Working with Closures and Iterators
-
Learn to define and use closures, including capturing variables from the environment.
-
Explore iterators, including custom iterator implementations and combinators like map, filter, and fold.
-
Reason: Closures and iterators provide powerful abstractions for working with sequences and applying functional programming concepts.
-
Example Task: Write a closure that filters a list of integers, keeping only even numbers, and return the result as a Vec.
-
-
Macros and Code Generation
-
Learn to create and use macros in Rust, including declarative macros with macro_rules! and procedural macros.
-
Explore how to write custom derive macros and use them to generate code based on type definitions.
-
Reason: Macros are a powerful metaprogramming tool in Rust that can reduce boilerplate and enhance code expressiveness.
-
Example Task: Create a custom derive macro that automatically generates a method for serialising a struct into JSON.
-
-
Building and Using Libraries
-
Understand how to structure and publish Rust libraries, including managing dependencies and writing documentation.
-
Learn to create and use feature flags and explore best practices for designing reusable and composable libraries.
-
Reason: Building and using libraries effectively is essential for contributing to and leveraging Rust's ecosystem.
-
Example Task: Develop a Rust library with modular components, publish it to crates.io, and implement comprehensive documentation and tests.
-
-
File I/O and Working with the Filesystem
-
Learn to perform file input/output operations using Rust’s standard library, including reading, writing, and managing files.
-
Explore techniques for handling large files, streaming data, and working with directories.
-
Reason: File I/O is a common requirement in many applications, and understanding how to do it efficiently in Rust is crucial.
-
Example Task: Write a program that reads a large file line by line and counts the number of occurrences of a specific word. Create a cli tool that performs a simple task of reading and writing from/to file.
