zig-spec VS warp

Zig's grammar is specified as a PEG: https://github.com/ziglang/zig-spec/blob/master/grammar/README.md

That's a bit like asking „what does * represent in C?“. It's a character. It is used in several syntactic constructs. Grepping for it in the grammar yields

I believe the precise definitions you're looking for will be apart of the language specification which is planned to live here "https://github.com/ziglang/zig-spec". However, Zig has not written a formal specification yet. For now Zig just maintains the informal "language reference", which mostly serves to help developers learn the language and be a quick place to look things about the language.

I tried warp [0] and I am unimpressed so far. Pretty complex, limited documentation, buggy. The builder paradigm they used feels pretty constrained and, in my opinion, achieve the opposite of the simplicity it is supposed to bring. I was surprised it is so popular.

Maybe I need more time or a favorable comparison to another framework to appreciate it.

Have you gone through the (examples)[https://github.com/seanmonstar/warp/blob/master/examples/]? There's actually a lot of explicit instructions here on how to use Warp, and all of them are very straightforward to read (e.g., (this example with route parameters and a POST'ed body)[https://github.com/seanmonstar/warp/blob/master/examples/body.rs])

There are numerous guides how to do custom error messages using the routes .recover() method (including the official one ), but it seems quite inflexible since I can't (seem to?) pass the actual error messages back to user.

What I see on the examples for the warp crate is that the examples do this:

You might want to consider using Alacritty instead of Warp. Warp is VC-funded, macOS only, closed source, and it phones home. They also kinda stole the name of a web framework.

warp server,

Hello, I'd need some help with warp routes since I'm not familiar with the framework. If somebody knows how to do this I'd appreciate very much.

If one were to undertake a project of developing something like this, which is the best web framework for it. I did some cursory research and discovered these back-end frameworks - actix, axum, poem, salvo, warp, gotham and rocket.

We've added support for the warp, salvo & thruster frameworks
