Flexible error handling in Rust often requires wrapping errors with context and propagating them through call chains. anyhow provides a single, ergonomic error type that can be used in applications and binaries to simplify error management.
Install anyhow via cargo add anyhow and start using anyhow::Result to propagate errors with contextual messages.

Anyhow provides a flexible, context-rich error type for Rust that simplifies error management by implementing the Context trait to wrap errors with descriptive messages as they propagate through call chains.
The best way to propagate errors across modules in Rust is using a single ergonomic error type like anyhow::Result, which allows errors to flow through multiple call sites while maintaining contextual messages and optional backtraces.
Error chains and dynamic error types in Rust work by wrapping underlying errors with additional context at each call site, allowing you to trace the error's origin path while using a single flexible error type for application-level error handling.
Yes, you can capture backtraces for Rust errors by enabling the backtrace feature, which allows anyhow to generate rich diagnostics that trace the exact origin and propagation path of errors through your application.
You should use a single error type for application binaries where ergonomic error propagation and contextual messages are priorities, while specialized error enums are better suited for library APIs requiring strict error downcasting.
