rusty_alloc-api

The safe Rust surface over rusty_alloc, a pure-Rust remake of mimalloc that measures at-or-below mimalloc on instructions retired for real programs (lua 0.97x, perl 0.99x, sqlite 1.00x) and below jemalloc across the board (lua 0.84x, perl 0.89x, sqlite 0.98x), while detecting double frees that upstream silently accepts and carrying no data race on its free path.

Status: 1.0.0 — the API is frozen. See the rusty_alloc crate page for the performance evidence and its scope (instruction counts, not wall-clock).

Upgrade from 0.3.x or earlier — mandatory. 0.4.0 fixed three platform-independent use-after-frees; treat 0.3.2 and earlier as unsound on every target.

What it gives you

GlobalAlloc — drop it in as #[global_allocator].
First-class heaps — create independent heaps, allocate from them, destroy them wholesale.
Allocator — the unstable allocator_api trait, behind a feature.

use rusty_alloc_api::RustyAlloc;

#[global_allocator]
static ALLOC: RustyAlloc = RustyAlloc;

fn main() {
    let v: Vec<u64> = (0..1000).collect();
    println!("{}", v.len());
}

Features

debug_checks, secure, profile — each forwards to the identically-named feature on rusty_alloc.

The Remade With Rust ecosystem

Remade With Rust is an initiative by Mata Network to rebuild essential C and C++ tools in Rust — for the memory safety, the predictable performance, and the freedom of a permissive license. Each project is a reimplementation, not a fork: same wire protocols and file formats, new code you can actually depend on.

We build the core to production grade and open-source it so the community can extend it. No copyleft. No surprises. Just the tools we rely on, made faster and safer.

Project	What it is
🎬 remade_ffmpeg_rs	Our FFmpeg alternative. Drop-in `ffmpeg` and `ffprobe` binaries — demux → decode → filter → encode → mux, rebuilt as composable Rust crates with zero GPL/LGPL. Apache-2.0. `rusty_h264` is its H.264 codec.
🧠 FFAI	*Our sister project: media for* AI. "The AI media toolkit, remade with rust." Embedded ASR + TTS (Mercury), OCR (Carmenta) and vision-language captioning (Argus**) behind an ffmpeg-style, swap-by-name architecture — no Python, no CUDA. MIT OR Apache-2.0.
🌐 Mata Network	The home page. "Stop sacrificing your privacy for convenience." Sovereign, self-hostable privacy infrastructure — wallet & identity, password manager, contact manager, and a browser extension that stops information leaking as you browse. Remade With Rust is its open-source arm.
