Usage

This library is available on crates.io and can be used by adding the following to your project's Cargo.toml:

[dependencies]
malloced = "1.3.1"

The star of the show is Malloced, Box-like pointer that calls free on Drop:

use malloced::Malloced;

MSRV

This library's minimum supported Rust version (MSRV) is 1.64. A new version requirement would result in a minor version update.

FFI Safety

Malloced<T> is a #[repr(transparent)] wrapper over NonNull<T>, so it can be safely used in C FFI. For example, the following is safe and even compiles with the improper_ctypes lint enabled:

#[deny(improper_ctypes)]
extern "C" {
    fn my_array_malloc() -> Malloced<[u8; 32]>;
}

Alternatives

• malloc_buf
• mbox
