Lo – simple WASM native language
Nice work. Out of curiosity, did you consider using pest (https://pest.rs/) to help build your parser? Or is it too much for what you are doing?

Jasmine, A rust-like programming language that compiles to Java
I had recently completed the first year of my Computer Science class at school and will begin my second year soon. My schools' class forces the use of Java programming language, and I absolutely hated it. So, over the course of a little less than a month, I wrote my own programming language, in Rust (objectively best programming language), using pest, to be as similar to Rust as possible, but compiling to Java.

What is the state of the art for creating domain-specific languages (DSLs) with Rust?
I second pest.rs. Using it is fairly intuitive and there's also a live playground on their website which is great for quickly developing and testing your AST (abstract syntax tree) parser for whatever language you're implementing.

Finding a Crate to Help with Terminal Program Interface
This is where you'll run into trouble. People who write parsing-related Rust crates generally write things like pest that expect their syntax to be defined completely at compile time so the parser can be run through the compiler's optimizers for best performance.

easy way to produce a parser
Give https://pest.rs a try.

What is your opinion about lifetime of data generated from a parsing
For now I have used pest to generate an AST that borrows from the given input. But if I can manage to make the parser generic over the return type it may be worth a refactoring.
- Is there a parsing library (lexer?) which can handle generic tokens?

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).

Hey Rustaceans! Got an easy question? Ask here (42/2021)!
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.
What are some alternatives?
When comparing pest and combine you can also consider the following projects:
nom - Rust parser combinator framework
lalrpop - LR(1) parser generator for Rust
rust-peg - Parsing Expression Grammar (PEG) parser generator for Rust
pom - PEG parser combinators using operator overloading without macros.
chumsky - Write expressive, high-performance parsers with ease.
chomp - A fast monadic-style parser combinator designed to work on stable Rust.
git-journal - The Git Commit Message and Changelog Generation Framework :book:
rust-csv - A CSV parser for Rust, with Serde support.
