Bump to 0.3.20
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.
[dependencies] backtrace = "0.3"
Note that this crate requires cc and ar to be present on Unix systems when libbacktrace is used (which is the default). For configuring C compilers see the cc crate documentation.
To simply capture a backtrace and defer dealing with it until a later time, you can use the top-level Backtrace type.
extern crate backtrace; 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.
extern crate backtrace; 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 }); }
