Detailed memory benchmarks (memory profiling) #369
Description
I've been using dhat-rs for memory profiling my Rust code. It shows exact stack traces of where allocations occur which has been extremely useful for optimizing my code. You can find more details about the output here. There's even a tool to generate flamegraphs from its output. Are there plans to add this type of functionality to Codspeed?

Yes definitely this is planned. At the moment, we have the memory instrument tracking allocations: https://codspeed.io/docs/instruments/memory
But having the call stack information of each allocation is definitely on the roadmap as it will also significantly helps agents optimize memory consumption

This will be great

Hey @ok-nick @jlucaso1 , we now support Memory Flamegraphs in the
memoryinstrument as of codspeed v5.4.0:You can find more information on how to setup the memory instrument here: https://codspeed.io/docs/instruments/memory
