Sesame, salt, and substance. A flagship bake.
Summary
The article discusses Rust error handling approaches, focusing on using standard library features instead of popular third-party dependencies like anyhow, thiserror, and eyre. The author explains their personal preference for writing errors without external dependencies, acknowledging this isn't necessarily the idiomatic Rust way but rather their preferred approach. The content appears to be a technical guide or personal reflection on Rust programming practices.
Key quotes
· 4 pulledRust error handling is a complex topic mostly due to the composability it gives you and no 'blessed way' to accomplish this from the community.
