Expand description

This trait is implemented on all the errors generated by the error_chain macro.

Associated Types

Associated kind type.

Required methods

Constructs an error from a kind, and generates a backtrace.

Constructs a chained error from another error and a kind, and generates a backtrace.

Returns the kind of the error.

Iterates over the error chain.

Returns the backtrace associated with this error.

Extends the error chain with a new entry.

Provided methods

Returns an object which implements Display for printing the full context of this error.

The full cause chain and backtrace, if present, will be printed.
