GC Pauses and Latency: The Hidden Cost of High-Level Languages
Java, Python, and JavaScript offer convenience, but garbage collection introduces unpredictable latency. Explore how runtime memory management affects performance in real systems.
C Gives You Control, But at What Cost?
C avoids garbage collection and gives manual memory control, but opens the door to dangerous bugs. Explore real-world memory issues and why they matter.
Rust: Memory Safety Without Garbage Collection
Rust gives you the performance of C with memory safety enforced at compile time. Learn how ownership and borrowing eliminate entire bug classes.
Rust's Stateful Closures: Passing and Mutating Across Multiple Calls
Managing stateful closures in Rust for repeated function calls
impl Fn() vs. Box<dyn Fn()>: Rust's Closure Dispatch Showdown
Comparing static and dynamic dispatch for closures in Rust, focusing on performance and use cases
What are move closures (move || { ... })? When are they necessary, and how do they interact with ownership?
What move actually moves, when you genuinely need it (threads, returned closures, async blocks), and how it interacts with ownership.
How do into_iter(), iter(), and iter_mut() differ?
into_iter(), iter() and iter_mut() differ in what they hand you: the value, a shared reference, or an exclusive one.
What are the differences between Fn, FnMut, and FnOnce?
Fn, FnMut and FnOnce aren't traits you pick — the compiler derives them from how the closure uses what it captured.
How do you specify a closure as a function parameter or return type?
Taking and returning closures: when impl Fn is enough, when you need Box<dyn Fn>, and what each choice costs at the call site.
