Function RegisterMultiCauseEncoder

errbase/encode.go:360–368

RegisterMultiCauseEncoder can be used to register new multi-cause error types to the library. Registered types will be encoded using their own Go type when an error is encoded. Multi-cause wrappers that have not been registered will be encoded using the opaqueWrapper type.

(theType TypeKey, encoder MultiCauseEncoder)

// that have not been registered will be encoded using the
// opaqueWrapper type.
func RegisterMultiCauseEncoder(theType TypeKey, encoder MultiCauseEncoder) {
	// This implementation is a simple wrapper around `LeafEncoder`
	// because we implemented multi-cause error wrapper encoding into a
	// `Leaf` instead of a `Wrapper` for smoother backwards
	// compatibility support. Exposing this detail to consumers of the
	// API is confusing and hence avoided. The causes of the error are
	// encoded separately regardless of this encoder's implementation.
	RegisterLeafEncoder(theType, encoder)
}

// MultiCauseEncoder is to be provided (via RegisterMultiCauseEncoder
// above) by additional multi-cause wrapper types not yet known to this
