Is Rust really safe? How to identify functions that can potentially cause panic

• rustig

  A tool to detect code paths leading to Rust's panic handler

  

There’s the rustig tool (https://github.com/Technolution/rustig) that looks for code paths leading to the panic handler. Not sure if it still works though.

• findpanics

  Find calls to panic functions in rust executables

Try findpanics (https://github.com/philipc/findpanics) instead. It's also unmaintained, but several years more recent.

• rust_fallible_vec

  Fallible allocation support for Rust's Vec

  

Does this or this look so alien that it could never end up in the standard library?

• fallible_collections

  3 28 3.9 Rust

  impl fallible collections in rust, quite as describe in RFC 2116

Does this or this look so alien that it could never end up in the standard library?

  12 515 4.2 Rust

  Discontinued Attribute macro to require that the compiler prove a function can't ever panic

'Hacks' such as https://github.com/dtolnay/no-panic, https://crates.io/crates/no-panics-whatsoever that ensure any calls to panic handling will result in link errors. Not really reliable in terms of being able to abort instead, but a possible tool.

  A modern TLS library in Rust

  

I believe it is more relevant than you think: servers running in containers, web assembler tasks running in browsers, embedded devices and kernels with total control of the system, all have the ability to do something more sensible than plain out SIGABRT or similar, and in many the case is not that the complete system is falling down. For example RustTLS is looking into allowing fallible allocators and as a pretty general-purpose library that seems like a nice feature. I do wish ulimit -v worked in a sensible manner with applications.
