Unix signals are a complicated mess burdened with decades of legacy decisions. However, async Rust gives us the means to handle them effectively in services and command-line tools. In this talk, we'll explore ways to use async Rust to bring these powerful but idiosyncratic tools to bear on...
Rust & Tell Berlin September 2021 - Michał Rostecki: Developing and managing eBPF programs with Rust
...We then attach it to the
kernel clone function and here, here it's just like, yeah, signal handling and showing
dots that it's running. So yeah, let's check this out, how it works. Well, similar to the
other examples I showed, but yeah, it's all Rust...

Rust is a systems language ready for IoT. In this talk, we’ll learn how to move servos, make sensor measurements, and speak low-level communication...
Crash Course with Bastion— Mahmut Bulut
Crash Course with Bastion— Mahmut Bulut [re-uploaded to correct formatting issue]
From the Berlin Rust's November "Rust and Tell" Meetup (https://www.meetup.com/Rust-Berlin/)
Mahmut talks about current asynchronous execution patterns, fault-tolerance, and error handling in Rust and how...
...oh wait does it make sense it doesn't make sense to represent a mutable signal with mute for obvious reasons um it's much better to remove the mutes and and actually handle your struct into the appropriate way not you know basic in to the easy way um...
...a new handle by just incrementing the count on this tls then we stash onto that handle id a clone of ourselves then we serialize a struct named value handle marker that was this sort of weird binary one under under mini changer on the value handle um then we...
...of defaults for signals uh which means if you don't catch for example term signal or interrupt signal uh your process just ignores that SC like if you type contrl c on any interactive things that run by Docker it usually just ignores the signal uh so in Vaga...
...another thread signals the notification that it bound then the thread will wake up and be able to handle the fact that it was signaled and this can be used to interrupt the flow i'm running or hung operations or in a device driver for handling an interrupt and...
...What will happen there is now you need to go and do all sorts of error handling and you what someone asked the question at the end of last talk um can you pass in an arbitrary value across the rust C boundary all of these languages right like you...
Rust Linz, January '22 - Error Handling in Rust - A Pragmatic Approach by Luca Palmieri
Luca's talk is based on this article: https://www.lpalmieri.com/posts/error-handling-rust/
Rust does not rely on exceptions - errors are values, handled via the `Result` enum. Calling a fallible function forces you...
...I think um and then of course we have also investigated lip signal. Um but um lip signal is C and um that probably the reason is probably not is that is a pretty old library so they didn't start on rest for that reason I'm assuming. Um...
...hoping for soon seeing is that people who write from macros to handle these cases better so I seen some people in incremental crates for inflation since then what kind of crop records you have not so handling trans they mainly around serialization between why and what not humbling funny...
...handle concurrency uh on embedded systems like how do you do multiple things at the same time so for example you might have an embedded system which is like blinking a light to indicate some status to the user and then controlling some motors with some timers and then handling...
Could you write a Rust program that never, ever has to stop? Not even for configuration changes or binary upgrades? One that will handle the traffic for thousands of applications on many more virtual machines that get up and down at any time? The Sōzu HTTP reverse proxy is there...
...public so what let us use it there's a couple ways to deal with that you could have a separate match rules that handles the extra train comma that's up to you you could use a star at the end so you can have zero or more trailing...
...so let me give you a a sense for what all of that looks like um so you have a network manager that that handles the connections we have a cryptography Suite we call vld d0 which is sort of a blessed set of different protocols um You Blake 3...
...the result type for handling recovery errors which i'll talk through um later in the slides um and yeah irrecoverable errors are signaled using panic again which i'll go through so recoverable errors these are obviously areas that we know how to handle um and you know in...
...references being passed and then you have returned as a reference as well then rust will get would not know how to handle that because it can handle it on its own but not through their lifetime syntax it's like because it's more dynamic like we don't...
...is something they can query the pty and the pty can also send these signals back to the shell like there is a uh like posix system there's systems there's a segwinch signal that is sent to the shell and tells the shell that the window size has...
...just not having the data we might not be able to answer questions but we also don't need to worry about how to handle the data after all the second principle is building security as i said not having the data is obviously the best part but we still...
