Function RegisterWrapperDecoder

errbase/decode.go:171–177

RegisterWrapperDecoder can be used to register new wrapper types to the library. Registered wrappers will be decoded using their own Go type when an error is decoded. Wrappers that have not been registered will be decoded using the opaqueWrapper type. Note: if the error type has been migrated from

(theType TypeKey, decoder WrapperDecoder)

// or a different type, ensure that RegisterTypeMigration() was called
// prior to RegisterWrapperDecoder().
func RegisterWrapperDecoder(theType TypeKey, decoder WrapperDecoder) {
	if decoder == nil {
		delete(decoders, theType)
	} else {
		decoders[theType] = decoder
	}
}

// WrapperDecoder is to be provided (via RegisterWrapperDecoder above)
// by additional wrapper types not yet known to this library.
