Stack Error – ergonomic error handling for Rust

In plain words

Stack Error is a Rust library that simplifies error handling by reducing initial design overhead. It aims to provide ergonomics comparable to anyhow while delivering informative error messages for debugging and typed data for runtime error handling. The tool is designed for Rust developers building libraries and applications who want straightforward error management without extensive upfront planning.

From the sources

A pragmatic error handling library for Rust that provides helpful strings for debugging, and structured data for runtime error handling. - gmcgoldr/stackerror

Stack Error reduces the up-front cost of designing an error handling solution for your project, so that you focus on writing great libraries and applications. Stack Error has three goals: Build informative error messages for debugging with minimal effort. The error message is co-located with the error source, which helps document your code. use stackerror :: prelude :: * ; pub fn process_data ( data : & str ) -> StackResult < String > { let data : Vec < String > = serde_json :: from_str ( data ) . map_err ( StackError :: from_msg ) . stack_err_msg ( fmt_loc ! ( "data is not a list of strings" ) ) ? ; data . first ( ) . cloned ( ) . ok_or_else ( StackError :: new ) . with_err_msg ( fmt_loc !…from github.com

  I'm making a dynamic language in Rust2022 · github.com · ▲184

  An implementation of a dynamic programming language in Rust. Includes: Parser&#x2F;Compiler, REPL, Virtual Machine, Bytecode Disassembler This started out as a learning project to teach myself Rust. It has grown into a decently substantial piece of software and I've learned quite a bit in the process! Some neat things: + A garbage collector that can store dynamically sized types without any double-indirection (i.e. I have my own Box implementation with manual alloc&#x2F;dealloc) + The smart pointer used to reference GCed data is a thin pointer. The ptr metadata needed for DSTs is stored in…

  Typed-arrow – compile‑time Arrow schemas for Rust2025 · github.com · ▲48

  Hi community, we just released https:&#x2F;&#x2F;github.com&#x2F;tonbo-io&#x2F;typed-arrow. When working with arrow-rs, we noticed that schemas are declared at runtime. This often leads to runtime errors and makes development less safe. typed-arrow takes a different approach: - Schemas are declared at compile time with Rust’s type system. - This eliminates runtime schema errors. - And introduces no runtime overhead — everything is checked and generated by the compiler. If you’ve run into Arrow runtime schema issues, and your schema is stable (not defined or switched at runtime), this project…

  Cppmatch – Rust-Like Pattern Matching and Error Handling for C++2025 · github.com · ▲42

  I've created cppmatch, a lightweight, header-only C++ library that brings Rust-inspired pattern matching and error handling to C++. It tries to imitate the functionality of the questionmark (?) operator in C++ by using a macro that uses the gcc extension https:&#x2F;&#x2F;gcc.gnu.org&#x2F;onlinedocs&#x2F;gcc&#x2F;Statement-Exprs.html This allows to create exceptionless code with non-intrusive error-as-value that unlike Exceptions, makes it clear which kinds of error a function can generate and forces you to handle (or ignore) them. The ? operator translates to *expect* To handle the errors I…

  Talanoa▲340

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Tapflow 2.0▲1,125

  We built Tapflow for devs, designers, PMs, and tech folks who’ve been sitting on internal docs, templates, and systems — but never productized them. Upload a PDF, notes, or workshop deck, and Tapflow drafts a structured product (with chapters, teaser and pricing plans). It’s good for AI kits, onboarding guides, design systems, and frameworks. You can sell through Stripe, LemonSqueezy, or PayPal. Real-time collaboration is in early beta. No site builder, no LMS — clean design and just focused tools to ship. Fully bootstrapped and just launched on PH today →…
