Rust: Investigating an Out of Memory Error
TL;DR: We discovered the hard way that when backtrace is enabled, the anyhow library is capturing a backtrace on every error. Only when printing this error in debug format!(”err: {:?}”, error) backtrace’s symbols are resolved to human-friendly names, thus leading to a significant memory increase for your application…
