Zig Memory Safety Modes

introduce an actually memory safe (unlike Rust) compilation mode inspired by Fil-C #36237 Based on prior art: Fil-C Currently Zig has: pub const Optimize = enum { /// Safety checks enabled. Optimize for bug detection, accurate debugging. debug, /// Safety checks enabled. Optimize for runtime performance. safe, /// Safety checks disabled. Optimize for runtime performance. fast,

A screenshot of a Zig GitHub issue proposes an actually memory-safe compilation mode inspired by Fil-C, contrasting it with Rust. The joke is that Zig’s existing optimization modes are humorously presented as safety choices: debug for bug detection, safe for performance, and fast with safety checks disabled. It is shared as a programming-language reaction to debates about memory safety and Rust versus Zig.
