derive(Error)
derive(Error) for struct and enum error types
This is a Rust crate that provides a convenient derive macro (#[derive(Error)]) for implementing std::error::Error on your custom error types (structs or enums). The goal is to enable library authors to build expressive, typed error types, with readable Display implementations (via #[error("...")] annotations) as well as From conversions (#[from]), source tracking (#[source]), and optionally backtraces. It is designed so that switching from handwritten error implementation to using this error is not a breaking change: you retain the same API. ... -

Anyhow
Flexible concrete Error type built on std::error::Error
This is a Rust library (crate) that provides a flexible, concrete error type built atop the standard std::error::Error trait. Its primary goal is to make error handling in applications easy: instead of defining lots of custom error types, you can use anyhow::Error (or the alias anyhow::Result<T>) for fallible functions. The crate supports attaching context to errors, so you can convert a low-level error (like “file not found”) into one with richer diagnostics (“Failed to read instructions from path X”) using .context() or .with_context(). ... -

Comprehensive Rust
This is the Rust course used by the Android team at Google
...Originally created for Google engineers, it has since been released publicly for the broader developer community. The course is structured into modular lessons that cover the fundamentals of Rust, including ownership, lifetimes, traits, generics, and error handling, before progressing to advanced topics like concurrency, async programming, unsafe Rust, and FFI. It is designed to be taught in classroom settings but can also be followed independently, making it useful both for structured training and self-study. The materials are presented in a slide-based format with accompanying examples and hands-on exercises to reinforce key concepts. ... -

Kreuzberg
Polyglot document intelligence framework
...It emphasizes modular design so that developers can define discrete tasks or “actions” and then compose them into complex flows where dependencies, parallel steps, and error handling are declaratively managed. This structure makes it simpler to build resilient automation pipelines that span multiple technologies or APIs without needing to glue everything together manually. The platform also supports observability and monitoring, helping teams trace the progression of workflows, catch errors early, and evaluate performance trends in orchestrated systems. -

Vaultwarden
Bitwarden compatible server written in Rust
...This will preserve any persistent data under /vw-data/, you can adapt the path to whatever suits you. Some web browsers, like Chrome, disallow the use of Web Crypto APIs in insecure contexts. In this case, you might get an error like Cannot read property 'importKey'. To solve this problem, you need to access the web vault from HTTPS. This can be configured in vaultwarden directly or using a third-party reverse proxy (some examples). If you have an available domain name, you can get HTTPS certificates with Let's Encrypt, or you can generate self-signed certificates with utilities like mkcert. ... -

LOL HTML
Low output latency streaming HTML parser/rewriter with CSS API
...The tag scanner may also sometimes switch the parser to the Lexer - if it requires additional tag information for the parsing feedback simulation. Having two different parser implementations for the same grammar will increase development costs and is error-prone due to implementation inconsistencies. We minimize these risks by implementing a small Rust macro-based DSL which is similar in spirit to Ragel. -

defmt
Efficient, deferred formatting for logging on embedded systems
defmt ("de format", short for "deferred formatting") is a highly efficient logging framework that targets resource-constrained devices, like microcontrollers. In its current iteration defmt mainly targets tiny embedded devices that have no means to display information to the developer, e.g. a screen. In this scenario, logs need to be transferred to a second machine, usually a PC/laptop, before they can be displayed to the developer/end-user. -
