Explain
Rust is a compiled, multi-paradigm language emphasizing memory safety without garbage collection.
It uses ownership, borrowing, and lifetimes to provide deterministic safety at compile time.
Designed for system programming, WebAssembly, cloud services, and performance-critical applications.
Core Features
Ownership, borrowing, lifetimes
Traits and generics
Pattern matching
Async/await
Smart pointers and interior mutability
Basic Concepts Overview
Ownership and borrowing
Variables and shadowing
Functions and closures
Structs and enums
Traits and generics
Error handling with Result/Option
Project Structure
src/ for main code
Cargo.toml for manifest
target/ for compiled binaries
tests/ for integration tests
examples/ for demo programs
Building Workflow
Create project with cargo new
Write code in src/main.rs or lib.rs
Build with cargo build
Run with cargo run
Test with cargo test
Difficulty Use Cases
