    modules are meant to be the boundary for a safe abstraction, but sometimes you get fun holes like https://github.com/rust-lang/rust/issues/128872 where you can implement Copy for a type in a different module in the same crate, even if the fields are private

    >Use Zig as a zero-dependency, drop-in C/C++ compiler that supports cross-compilation out-of-the-box.

    I know barely anything about Zig, so I don't know the veracity of this, however.

    Rust's FFI also relies on undefined behavior if this comment isn't outdated https://github.com/rust-lang/rust/pull/59625#issuecomment-48... https://github.com/rust-lang/rust/blob/master/library/core/s... . Might not be an issue as long as the implementation is only used with LLVM and LLVM doesn't change.

    Mountpoint is a new FUSE based solution written in the Rust programming language and based on a Rust version of the Linux FUSE library. See here for an explanation of the choice of Rust. Other popular tools in the FUSE-based family of solutions are goofysand s3fs.
  • Ada crate of the year 2024 announced
    2 projects | news.ycombinator.com | 9 Feb 2025
    Yep, and even without dynamic memory management, Ada is not type-safe: https://www.enyo.de/fw/notes/ada-type-safety.html

    Rust also has problems: https://github.com/rust-lang/rust/issues/25860

  • It Is Time to Standardize Principles and Practices for Software Memory Safety
    3 projects | news.ycombinator.com | 6 Feb 2025
    The bug used by that repository [1] isn't the only one that can be used to escape the Safe Rust type system. There are a couple others I've tried [2] [3], and the Rust issue tracker currently lists 92 unsoundness bugs (though only some of them are general-purpose escapes), and that's only the ones we know about.

    These bugs are not really a problem in practice though as long as the developer is not malicious. However, they are a problem for supply chain security or any case where the Rust source is fully untrusted.

  • Roc Rewrites the Compiler in Zig
    4 projects | news.ycombinator.com | 4 Feb 2025
    Since at least 2018, there's been a planned upgrade to the borrow checker to permit certain patterns that it currently rejects [0]. Also since 2018, there's been an implementation of the new version (called Polonius) that can be enabled with an unstable compiler flag [1].

    But it's 2025, and the new version still hasn't been enabled on stable Rust, since the Polonius implementation is seen as too slow for larger programs. A big goal of the types team since last year has been to reimplement a faster version within rustc [2].

    I'd count this as a language feature (albeit a relatively minor one) that's been greatly deferred in favor of shorter compile times.

  • Rust's worst feature (available in Rust nightly)
    1 project | news.ycombinator.com | 30 Jan 2025
    > Is there evidence more baking won't happen?

    No, actually there is a lot of evidence that it will still be worked on.

    Normally I would just say look at the issue linked in the nightly docs but due to an overlap of tacking PR and moving it from std to core PR it's not supper useful.

    Tracking Issue: https://github.com/rust-lang/rust/issues/78485

    If the author has constructive critique they should probably mention it there (after skimming through the discussion to make sure this wasn't already considered and not done due to subtleties they overlooked in the blog post (like e.g. that it's a standard/core feature which has to work across all targets and as such can't rely on anything being initialized to 0 by the OS, or that depending on the global allocator used you definitely can't rely on things being zeroed even if the OS only hands out zeroed memory, etc. etc.))

What are some alternatives?

When comparing mimalloc and rust you can also consider the following projects:

jemalloc

carbon-lang - Carbon Language's main repository: documents, design, implementation, and related tools. (NOTE: Carbon Language is experimental; see README)

rpmalloc - Public domain cross platform lock free thread caching 16-byte aligned memory allocator implemented in C

zig - General-purpose programming language and toolchain for maintaining robust, optimal, and reusable software.

snmalloc - Message passing based allocator

Odin - Odin Programming Language

hardened_malloc - Hardened allocator designed for modern systems. It has integration into Android's Bionic libc and can be used externally with musl and glibc as a dynamic library for use on other Linux-based platforms. It will gain more portability / integration over time.

Nim - Nim is a statically typed compiled systems programming language. It combines successful concepts from mature languages like Python, Ada and Modula. Its design focuses on efficiency, expressiveness, and elegance (in that order of priority).

factorio-docker - Factorio headless server in a Docker container

hylo - The Hylo programming language

jemallocator - Rust allocator using jemalloc as a backend

go - The Go programming language
