Building with Rust
Create blazingly fast, memory-safe systems with the most loved programming language
Why Choose Rust?
🛡️ Memory Safety
Guaranteed memory safety without garbage collection. No null pointer crashes or data races.
⚡ Zero-Cost Abstractions
High-level features compile to efficient machine code. Performance of C with safety.
🔧 Modern Tooling
Cargo package manager, built-in testing, documentation, and formatting tools.
🦀 Fearless Concurrency
Write concurrent code without fear. The compiler prevents data races.

Rust Best Practices
Ownership & Borrowing
- Understand the borrow checker
- Use references when possible
- Clone only when necessary
- Leverage lifetimes properly
Error Handling
- Use Result<T, E> everywhere
- Create custom error types
- Propagate with ? operator
- Handle all error cases
Performance
- Profile before optimizing
- Use iterators over loops
- Minimize allocations
- Leverage SIMD when needed
Idiomatic Rust
- Follow naming conventions
- Use pattern matching
- Implement standard traits
- Write comprehensive tests
