# Zig is Adding Memory Safety.

**[YouTube](https://daily.dev/sources/youtube)** · 2 min read · 1 upvotes · 1 comments

## Summary

A YouTube-style commentary criticizes a proposal to add memory safety to the Zig programming language, inspired by Philip C-style compilation with an alleged 1-6x performance penalty. The speaker argues the proposal contradicts Zig's explicit allocator philosophy, disputes the claim that it would be 'actually memory safe unlike Rust,' and ties the timing to community infighting following the Bun team's rewrite from Zig to Rust. The speaker suggests Zig should reach 1.0 before pursuing this feature.

## Questions this post answers

### What is the Zig proposal to add memory safety to the language?

The proposal introduces a compilation mode, inspired by Fil-C, that lets developers compile projects, including entire trees of C or C++ dependencies, into an executable that is fully memory safe with no escape hatch, at a claimed 1 to 6x performance penalty. It works by having the compiler track extra pointer metadata at runtime rather than using a garbage collector.

_Developers weighing Zig's direction against Rust can follow how this memory-safety debate unfolds on daily.dev._

### How does Rust achieve memory safety compared to the proposed Zig memory-safe compilation mode?

Rust enforces memory safety primarily at compile time through its ownership and borrowing system, with an unsafe escape hatch for cases like foreign function interfaces or hardware interaction. The proposed Zig mode instead relies on runtime pointer metadata tracking, incurring a claimed 1 to 6x performance penalty rather than solving safety before the program runs.

_Anyone comparing Rust and Zig for systems work can track how each language's safety trade-offs evolve via daily.dev._

> As long as it stays a proposal it should be fine. I'm pretty sure Zig can figure this out without destroying their language.
