How to use rspotify?
Apologies for the stupid question but I'm fairly new to Rust and can't figure out for the life of me how to use the rspotify crate. As far as I can get with the documentation / examples is just that it isn't a regular application / binary of itself but just a crate, but I don't see why that's causing me issues. Whenever I try to run the following example, I get the following error, despite me trying to remove and rebuild the crate just in case.

Announcing the Keyword Generics Initiative
I have wanted async generics myself for some time now. In RSpotify, we have both async and blocking users, so we had to resort to maybe_async to switch between them. However, this macro has a few caveats and isn't as convenient as having it built-in.
- A delayed news: rspotify is 0.11 now
-
What if trait implementation _might_ be async or might not?
maybe_async accomplishes this by switching based on the feature flags enabled for your library. I found it in rspotify, but haven't actually given it a try myself.

Psst: 3rd-party Spotify client built with Rust and Druid
As a developer of rspotify I'm curious as to why you chose not to use an already existing API client for Spotify. Are there any problems you found? I do agree that the current version is a mess but we're working on a full rewrite for 0.10 and you might be interested in that.

Planespotting with Rust: using nom to parse ADS-B messages
Just in case you are not familiar with nom, it is a parser combinator written in Rust. The most basic thing you can do with it is import one of its parsing functions, give it some byte or string input and then get a Result as output with the parsed value and the rest of the input or an error if the parser failed. tag for example is used to recognize literal character/byte sequences.

Show HN: Rust nom parsing Starcraft2 Replays into Arrow for Polars data analysis
I may be the only one not familiar, but nom refers to https://github.com/rust-bakery/nom which looks like a pretty handy way to parse binary data in Rust.
-
Is this a good way to free up some memory?
Lots of people use nom for their parsing needs, but that's not the only game in town and there other options.
-
What is the state of the art for creating domain-specific languages (DSLs) with Rust?
As much as I love nom as well as other parser combinator libraries, regex-based parsers, BNF/EBNF-based parsers, etc. I always end up going back to plain old text-based char-by-char scanners.

What's everyone working on this week (22/2023)?
I am using nom / nom_locate to build the parser side because I've done a handful of other projects with it, and I plan to use tower-lsp to hook up the language server side.

Tokenizing
Look into a parsing library such as https://github.com/rust-bakery/nom

Something like pydantic but for just strings?
If we were in /r/learnrust I'd have recommended the nom crate for this.

lua bytecode parser written in rust
Thanks to the flexibility of [nom](https://github.com/rust-bakery/nom), it is very easy to write your own parser in rust, read [this article](https://github.com/metaworm/luac-parser-rs/wiki/Write-custom-luac-parser) to learn how to write a luac parser

Should I revisit my choice to use nom?
I've been working on an assembler and right now it uses nom. While nom isn't great for error messages, good error messages will be important for this particular assembler (current code), so I've been attempting to use the methods described by Eyal Kalderon in Error recovery with parser combinators (using nom).
