error-chain - Consistent error handling for Rust

error-chain is a crate for dealing with Rust error boilerplate. It provides a few unique features:

• No error is ever discarded. This library primarily makes it easy to "chain" errors with the chain_err method.
• Introducing new errors is trivial. Simple errors can be introduced at the error site with just a string.
• Errors can create and propagate backtraces.
