Meeseeks.Error exception (Meeseeks v0.17.0) View Source

Meeseeks.Error provides a generic error struct implementing the Exception behaviour and containing three keys: type, reason, and metadata.

type is an atom classifying the general context the error exists in, such as :parser.
reason is an atom classifying the general problem, such as :invalid_input.
metadata is a map containing any additional information useful for debugging the error, such as %{input: "..."}.
