Jun Wu 8315564c33 stackdesc: a thin library to annotate the current thread execution ... Summary: Add a thin library to store a side-by-side "stack" that can provide chainned human-friendly context information. Right now, it only works with the current native thread. It can be thought of an "annotation" of the native stack. The concept is useful for both Python and Rust. So this diff adds a Rust implementation, and a Python binding will be added as follow-up. This diff only implements the minimal bits to make it useful. Some future possibilities are: - Have a way to collect information from all threads. This requires a global state and customized thread spawn / join wrappers. - Have a way to "request" for the "stack description" from another thread. This might be useful for progress-bar use-case, where the progress bar logic runs in a different thread. Note: I searched through `crates.io` for something similar. But I couldn't find any. They are either coupled with error handling that will miss the "explain why this prefetch happens" case, or are not lazy, which is undesirable as I'd imagine some context to have complex logic like rendering a DAG graph.
