py-spy: a sampling profiler for python programs
This crate lets you use py-spy as a rust library, and gather stack traces from your python process programmatically.
§Example:
fn print_python_stacks(pid: py_spy::Pid) -> Result<(), anyhow::Error> {
// Create a new PythonSpy object with the default config options
let config = py_spy::Config::default();
let mut process = py_spy::PythonSpy::new(pid, &config)?;
// get stack traces for each thread in the process
let traces = process.get_stack_traces()?;
// Print out the python stack for each thread
for trace in traces {
println!("Thread {:#X} ({})", trace.thread_id, trace.status_str());
for frame in &trace.frames {
println!("\t {} ({}:{})", frame.name, frame.filename, frame.line);
}
}
Ok(())
