alloc_tracker 0.6.1

Memory allocation tracking utilities for benchmarks and performance analysis.

This package provides utilities to track memory allocations during code execution, enabling analysis of allocation patterns in benchmarks and performance tests.

Basic usage

use alloc_tracker::{Allocator, Session};

#[global_allocator]
static ALLOCATOR: Allocator<std::alloc::System> = Allocator::system();

fn main() {
    let session = Session::new();

    // Track a single operation
    {
        let operation = session.operation("my_operation");
        let _span = operation.measure_process();
        let _data = vec![1, 2, 3, 4, 5]; // This allocates memory
    }

    // When `session` is dropped it prints a human-readable summary to stdout and
    // writes machine-readable JSON files (one per operation) into the Cargo
    // target directory: target/alloc_tracker/<operation>.json.
}
