iai VS rust-socketio

The three popular options for benchmarking in Rust are: libtest bench, Criterion, and Iai.

Iai^1 uses CacheGrind^2 to count instructions

But, /u/bencherdev, please consider integrating iai measurements! By the same person behind criterion but designed for one-shot measurements that are stable in CI measurements.

Is lai no longer maintained? It hasn't had any commits in a year and a half.

Lately I've found that using unwrap_unchecked has nearly zero performance gain but all the UB to gain if you change the code one day. My source is iai which provides exact instruction counts and is entirely deterministic for any given execution (and almost-deterministic across different compilations of the same program).

Have you tried criterion.rs or iai ? The first is great at micro benchmarks and, if it is not enough, the second can catch even smaller performance difference.

In the mean time maybe https://github.com/bheisler/iai could be of help

Well, the most interesting one is probably Iai; an experimental benchmark framework that runs all of the benchmarks in Cachegrind for much higher precision and repeatability than is possible with Criterion.rs. It's still a work-in-progress, so I haven't published it on Crates.io yet. See the readme for a more detailed discussion of the pros/cons relative to Criterion.rs.

The world has moved on though to opinionated tools, and Rust isn't even the furthest in that direction (That would be Go). The equivalent of those two lines in Cargo.toml would be this example of a basic configuration from the jacoco-maven-plugin: https://www.jacoco.org/jacoco/trunk/doc/examples/build/pom.x... - That's 40 lines in the section to do the "defaults".

Yes, you could add a load of config for files to include/exclude from coverage and so on, but the idea that that's a norm is way more common in Java projects than other languages. Like here's some example Cargo.toml files from complicated Rust projects:

Servo: https://github.com/servo/servo/blob/main/Cargo.toml

rust-gdext: https://github.com/godot-rust/gdext/blob/master/godot-core/C...

ripgrep: https://github.com/BurntSushi/ripgrep/blob/master/Cargo.toml

socketio: https://github.com/1c3t3a/rust-socketio/blob/main/socketio/C...

Looks great! Was the motivation for creating this better integration with Tower? How does it compare to https://github.com/1c3t3a/rust-socketio . I haven't used either, but I was thinking about using the latter in an upcoming project. Now I am considering using this one.

So I set out to write a Socket.IO server by extending the existing crate rust-socketio.

I‘m working on the implementation of a socketio client in rust. https://github.com/1c3t3a/rust-socketio.
