stats_alloc

An instrumenting middleware for global allocators in Rust, useful in testing for validating assumptions regarding allocation patterns, and potentially in production loads to monitor for memory leaks.

Example

extern crate stats_alloc;

use stats_alloc::{StatsAlloc, Region};
use std::alloc::System;

#[global_allocator]
static STATS_ALLOC: StatsAlloc<System> = StatsAlloc::system();

fn example_using_region() {
    let reg = Region::new(&STATS_ALLOC);
    let x: Vec<u8> = Vec::with_capacity(1_024);
    println!("Stats at 1: {:#?}", reg.change());
    // Used here to esnure that the value isn't deallocated first
    ::std::mem::size_of_val(&x);
}
