A library for acquiring backtraces at runtime for Rust. This library aims to enhance the support of the standard library by providing a programmatic interface to work with, but it also supports simply easily printing the current backtrace like libstd's panics. Fork from https://github.com/rust-lang/backtrace-rs/tree/0.3.61.


pprof-backtrace = "0.3"


To simply capture a backtrace and defer dealing with it until a later time, you can use the top-level Backtrace type.

use backtrace::Backtrace;

fn main() {
    let bt = Backtrace::new();

    // do_some_work();

    println!("{:?}", bt);

If, however, you'd like more raw access to the actual tracing functionality, you can use the trace and resolve functions directly.

fn main() {
    backtrace::trace(|frame| {
        let ip = frame.ip();
        let symbol_address = frame.symbol_address();

        // Resolve this instruction pointer to a symbol name
        backtrace::resolve_frame(frame, |symbol| {
            if let Some(name) = symbol.name() {
                // ...
            if let Some(filename) = symbol.filename() {
                // ...

        true // keep going to the next frame
