Domain Specific Language embedded in Rust
Combine is also nice to use and actively developed.

Hey Rustaceans! Got an easy question? Ask here (9/2022)!
https://crates.io/crates/combine is a decent alternative to Nom. I found it much easier to pick up. I was using it to implement our generalized placeholder syntax in SQLx (which I hope to actually finish at some point): https://github.com/launchbadge/sqlx/blob/a2eda2de2462876a160982e57d73103795e34aa2/sqlx-core/src/placeholders.rs

Chumsky, a parser combinator crate that makes writing error-tolerant parsers with recovery easy and fun!
Nice to see support for error recovery with parser combinators! I never got to the point of adding it in combine as I swapped out my language parser(s) to use LALRPOP instead (implementing error recovery for it instead).

You may want to also look at some of the popular parser combinators like nom and combine. I don't think they do what you are suggesting, though.

Challenge accepted: announcing SurrealDB 2.0
Unlike the previous parser, which was based on the nom parser-combinator library, the new parser is an optimised recursive descent parser with a separate lexing step. This change allows for more efficient parsing by separating the tokenisation of the input from the parsing logic itself, streamlining the parsing process.

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
What are some alternatives?
