Crate tracing_samply 

tracing-samply

A tracing-subscriber layer that bridges tracing with samply.

Currently, this only records spans as markers using samply’s ad-hoc marker file format, which are then detected at runtime by samply and written to the profile.

Markers for a thread are only detected if samply is attached when the thread is created.

This crate will adapt to any changes upstream. The creator has expressed that the marker file is a temporary measure and that it will be replaced with a more robust solution in the future: https://github.com/mstange/samply/pull/143#issuecomment-2067747892
