# Run-time memory tracking and profiling.
Part of the [`rerun`](https://github.com/rerun-io/rerun) family of crates.

This is a library for tracking memory use in a running application.
This is useful for tracking leaks, and for figuring out what is using up memory.
`re_memory` includes an opt-in sampling profiler for allocation callstacks.
Each time memory is allocated there is a chance a callstack will be collected.
This information is tracked until deallocation.
You can thus get information about what callstacks lead to the most live allocations,
giving you a very useful memory profile of your running app, with minimal overhead.
