Description
rustc inserts frames std::sys_common::backtrace::__rust_end_short_backtrace and std::sys_common::backtrace::__rust_begin_short_backtrace so that the internal backtrace implementation can filter out noise from backtrace capturing.
However those are not used when std::backtrace::Backtrace is displayed leading to incredibly verbose backtraces.
Maybe we could perform this filtering for "{}" but provide the unfiltered values for "{:#}"?
I tried this code:
fn setup() {
std::panic::set_hook(Box::new(|panic| {
println!("{}", std::backtrace::Backtrace::force_capture());
}));
}
fn run() {
panic!("OOPS");
}
fn main() {
setup();
run();
}I expected to see this happen:
