ChainedError

Struct ChainedError 

Source
pub struct ChainedError { /* private fields */ }
Expand description

A generic error which represents a linked-list of errors and exposes it with source(). It’s meant to be the target of a conversion of any Exn error tree.

It’s useful for inter-op with other error handling crates like anyhow which offer simplified access to the error chain, and thus is expected to be wrapped in one of their types intead of being used directly.
