Anyhow
Anyhow is a Rust crate that provides ergonomic error handling for applications. It centers on a single, dynamic error type called anyhow::Error, which can represent any error type at runtime and can be created from most error values. This design reduces boilerplate when errors are propagated through layered code, while still preserving rich error information.
Key features include a convenient macro and methods for adding context. The anyhow! macro creates an error
Backtraces are supported when compiled with the backtrace feature, capturing the call-site location to aid debugging.
Use cases and guidance: anyhow is well-suited for binary applications, prototypes, and other code paths where
In summary, anyhow emphasizes ergonomic error propagation and rich context for applications, trading some static error-type
