# rusty_alloc-api

The safe Rust surface over [`rusty_alloc`](https://crates.io/crates/rusty_alloc),
a pure-Rust remake of mimalloc that measures at-or-below mimalloc on
instructions retired — on real programs and on every operation of the per-op
scan — while detecting double frees that upstream silently accepts.

**Status: `0.7.0` — a 0.x release.** See the
[`rusty_alloc`](https://crates.io/crates/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.

```rust
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`.
