Adding `limit_alloc` library as a dependency

Run this command in a terminal, in your project's directory:

cargo add limit-alloc

To add it manually, edit your project's Cargo.toml file and add to the [dependencies] section:

limit-alloc = "0.1.0"

The limit_alloc library will be automatically available globally. Read the limit_alloc library documentation.

Back to the crate overview.

Readme

limit-alloc

A custom allocator that allows to limit the available memory.

Usage

use limit_alloc::Limit;
use std::alloc::System;

// Limit available RAM to 4MB
#[global_allocator]
static A: Limit<System> = Limit::new(4_000_000, System);

fn main() {
    let _huge_vec: Vec<u8> = Vec::with_capacity(4_000_001);
}

You can run that example locally and see how the process crashes:

$ cargo run --example huge_vec
memory allocation of 4000001 bytes failed
Aborted
