No Garbage Collector: How Rust Manages Memory Without GC
Go to Rust Series: ← Ownership and Borrowing | Series Overview | Lifetimes Explained → The Fundamental Trade-Off Go: Automatic memory management via garbage collection Rust: Compile-time memory management via ownership Both approaches have profound implications for performance, predictability, and developer experience. How Go’s GC Works Go: func allocateData() { for i := 0; i < 1000000; i++ { data := make([]byte, 1024) // Use data... // No explicit free needed } } Go’s GC: Tracks all allocations Periodically stops the world (STW) Scans for reachable objects Frees unreachable memory GC pause times: Typically 1-10ms, but can spike higher. ...
