ferroalloc-probe

A drop-in GlobalAlloc wrapper that streams every heap allocation and deallocation to the ferroalloc VS Code extension for real-time memory visualization.

Usage

# Cargo.toml
[dependencies]
ferroalloc-probe = "0.1"

use ferroalloc_probe::{FerroAllocator, start_flush_thread};

#[global_allocator]
static ALLOC: FerroAllocator = FerroAllocator;

fn main() {
    start_flush_thread(7777); // connect to ferroalloc-analyzer
    // ... rest of your program
}

Then run ferroalloc-analyzer and open your project in VS Code with the ferroalloc extension installed.

How it works

FerroAllocator wraps the system allocator and records every alloc/dealloc call. Source locations (file, line, function) are resolved at runtime inside your process using the OS symbol table — this avoids ASLR/DWARF mismatch issues on macOS.

Events are pushed into a lock-free queue and streamed over TCP to ferroalloc-analyzer.
