10///
11/// This mimics logs generated using //src/lib/diagnostics/data. These logs include:
12///   * A timestamp in nanoseconds when the log was generated.
13///   * The URL of the component generating the log.
14///   * The component moniker (https://fuchsia.dev/fuchsia-src/reference/components/moniker)
15///   * The log severity, e.g. fatal, error, warning, etc.
16///   * The log message.
17///
18/// See also `writer::Writer::log` which formats these entries for display.
