Rust's Iterator adaptors often compile to the same machine code as hand-written loops—but only when the optimizer can prove bounds safety. Here's how to verify it, where it breaks, and when to choose each style.
Lua coroutines can act as pull-style generators, replacing nested callbacks and intermediate tables with resumable producers. This post covers a worked example, API trade-offs, and cleanup pitfalls across Lua versions.
Learn how Rust's iterator chains and generic functions compile to assembly equivalent to hand-written loops, giving high-level code zero runtime overhead.
Rust iterator chains replace index bookkeeping with lazy, composable adapters. A worked filter/map/sum example, the laziness gotcha, borrowing choices, and when a plain loop is still the right call.
I am designing a small query layer in Zig that must return results in fixed-size pages rather than loading an entire dataset into memory. The data can be either an in-memory array or a file-backed stream, and I want a single abstraction that bounds each query to at most N items. From the standard library I see three relevant pieces: std.mem.slice for creatin
