Upgrade `ruzstd` `object`, and `addr2line` to the latest version (rust-lang/backtrace-rs#718) `object` released a breaking change with adjustments to `elf::R_RISCV_GNU_*` and `pe::IMAGE_WEAK_EXTERN_*` constants, as well as a changed API for Mach-O dyld. None of these are relevant to our use. `ruzstd` moved some API around to account for compression support, the only required update for us is to change import paths. `addr2line` only bumped the gimli version, which includes an update that will help us drop the crates.io compiler-builtins dependency from the standard library. Object changelog: https://github.com/gimli-rs/object/blob/master/CHANGELOG.md#0370 Ruzstd changelog: https://github.com/KillingSpark/zstd-rs/releases/tag/v0.8.0 Addr2line changelog: https://github.com/gimli-rs/addr2line/blob/master/CHANGELOG.md#0250-20250611
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"
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 }); }
The backtrace crate is a core component of the standard library, and must at times keep up with the evolution of various platforms in order to serve the standard library's needs. This often means using recent libraries that provide unwinding and symbolication for various platforms. Thus backtrace is likely to use recent Rust features or depend on a library which itself uses them. Its minimum supported Rust version, by policy, is within a few versions of current stable, approximately “stable - 2”.
This policy takes precedence over versions written anywhere else in this repo.
