Rust Skill Tree on LabEx

The Rust Skill Tree on LabEx is structured into several skill groups, each containing specific skills. Here's an organized overview:

Basics

Foundational Rust concepts:

• Syntax: Basic structure and commands.
• Data Types: Understanding primitive types, such as i32, f64, bool, and char.
• Variables: Declaring and using variables, including immutable and mutable variables.
• Operators: Arithmetic, logical, and comparison operators.
• Control Structures: if-else, loop, while, and for loops.
• Functions: Defining and calling functions.
• Comments: Annotating code with single-line and multi-line comments.

Ownership and Borrowing

The core Rust concepts of ownership and borrowing:

• Ownership: Understanding how Rust manages memory and the ownership rules.
• Borrowing: Referencing data without taking ownership, including mutable and immutable borrowing.
• Lifetimes: Ensuring references are valid and do not outlive the data they reference.

Data Structures

Rust's built-in and custom data structures:

• Tuples: Grouping multiple values of different types.
• Structs: Defining custom data types with named fields.
• Enums: Creating custom types with a set of variants.
• Arrays and Vectors: Storing collections of the same data type.

Error Handling

Handling errors and unexpected situations:

• Result: Representing the success or failure of an operation.
• Option: Handling the presence or absence of a value.
• Panics: Handling runtime errors and unwinding the call stack.
• Custom Errors: Creating and using custom error types.

Concurrency

Rust's concurrency features:

• Threads: Spawning and managing parallel execution.
• Shared State: Safely sharing data between threads using primitives like Mutex and RwLock.
• Channels: Communicating between threads using message-passing.

Standard Library

Rust's extensive standard library:

• Collections: Data structures like Vec, HashMap, and HashSet.
• I/O: Reading from and writing to files, the console, and network sockets.
• Strings and Text Processing: Working with Unicode-based strings.
• Math and Numerics: Mathematical functions and numeric types.

Crates and Modules

Organizing and sharing Rust code:

• Crates: Creating and using external crates (libraries).
• Modules: Organizing code into modules and submodules.
• Visibility: Controlling the accessibility of items within a module.

Testing and Documentation

Ensuring code quality and maintainability:

• Unit Tests: Writing and running tests for individual functions and modules.
• Integration Tests: Testing the interaction between components.
• Documentation: Generating documentation using rustdoc.
