Crate thresher 

A memory allocation wrapper that hits a callback when a threshold is reached:

use std::alloc;
use thresher::Thresher;

#[global_allocator]
// Wrap the standard system allocator
static THRESHER: Thresher<alloc::System> = Thresher::new(alloc::System);

fn main() {

    // Set the threshold we care about reaching
    THRESHER.set_threshold(100 * 1024 * 1024);

    // Set the callback when the threshold is reached (note: may be called multiple times)
    THRESHER.set_callback(|allocation| {
        println!("Threshold reached! Allocated: {} bytes", allocation);
    });

}
