public class LogField
extends ProxyInstance

Structure representing a single field in a structured log entry. See g_log_structured() for details.

Log fields may contain arbitrary values, including binary with embedded nul bytes. If the field contains a string, the string must be UTF-8 encoded and have a trailing nul byte. Otherwise, length must be set to a non-negative value.
