Function cloneMessage

pkg/session/session.go:428–432

cloneMessage returns a deep copy of a session Message. It copies the inner chat.Message's slice and pointer fields so that the returned value shares no mutable state with the original.

(m *Message)

// It copies the inner chat.Message's slice and pointer fields so that the
// returned value shares no mutable state with the original.
func cloneMessage(m *Message) *Message {
	cp := *m
	cp.Message = cloneChatMessage(m.Message)
	return &cp
}

// snapshotItems returns a copy of s.Messages safe to use without holding
// s.mu. Each Message value is deep-copied so concurrent UpdateMessage calls
