When Zig is safer and faster than Rust

The Roc language team rewrote their standard library from Rust to Zig, citing better tools for working in a memory-unsafe environment. The author tested this by building a bytecode interpreter in both unsafe Rust and Zig, finding Zig to be safer, faster, and easier to write. Issues with unsafe Rust include complexity with raw pointers and aliasing rules. Zig, designed for memory-unsafe operations, offers explicit allocation strategies, non-null pointers by default, and better ergonomics for pointers and slices, leading to improved developer experience and performance.
