currently the #[backtrace] attr has no option, and thiserror generated codes always use Backtrace::capture()
however, if user want some error always enable backtrace, they have to
- write
impl From<Err> Error manually
- or set env
RUST_BACKTRACE=1, but that will cause all backtraces are enabled, even they only want to enable a few error backtrace
if #[backtrace] add a new option force, like #[backtrace(force=true)], when user enable the force capture, thiserror generated codes can use Backtrace::force_capture() instead of Backtrace::capture()
