An allocator that can track and limit memory usage.

This crate provides a generic allocator that wraps another allocator, tracking memory usage and enabling limits to be set.

Example

It can be used by declaring a static and marking it with the #[global_allocator] attribute:

use std::alloc;
use cap::Cap;

#[global_allocator]
static ALLOCATOR: Cap<alloc::System> = Cap::new(alloc::System, usize::max_value());

fn main() {
    // Set the limit to 30MiB.
    ALLOCATOR.set_limit(30 * 1024 * 1024).unwrap();
    // ...
    println!("Currently allocated: {}B", ALLOCATOR.allocated());
}
