`only_alloc` wraps another allocator and disables deallocating memory within it.

It can be used either as a global allocator or as an allocator from `#![feature(allocator_api)]`.

It can be used with `no_std` environments and it contains zero dependencies.

```rs

use mimalloc::MiMalloc;

use only_alloc::GlobalOnlyAlloc;

#[global_allocator]

static ONLY_MIMALLOC: GlobalOnlyAlloc = GlobalOnlyAlloc(MiMalloc);

```

## Installation

```bash

cargo add only_alloc

```

## Why?

Maybe you have a use for this because I don't. It might be microscopically faster for CLI tools. I simply enjoyed writing it.
