- ---
-
- Discord.Net's clients provide a [Log] event that all messages will be
- dispatched over.
-
- For more information about events in Discord.Net, see the [Events]
- section.
-
- [Log]: xref:Discord.Rest.BaseDiscordClient.Log
- [Events]: events.md
-
- ### Usage
-
- To receive log events, simply hook the discord client's log method
- to a `Task` with a single parameter of type [LogMessage].
-
- It is recommended that you use an established function instead of a
- lambda for handling logs, because most addons accept a reference
- to a logging function to write their own messages.
-
- [LogMessage]: xref:Discord.LogMessage
-
- ### Usage in Commands
-
- Discord.Net's [CommandService] also provides a log event, identical
- in signature to other log events.
-
- Data logged through this event is typically coupled with a
- [CommandException], where information about the command's context
- and error can be found and handled.

- #### Tips
-
- Due to the nature of Discord.Net's event system, all log event
- handlers will be executed synchronously on the gateway thread. If your
- log output will be dumped to a Web API (e.g. Sentry), you are advised
- to wrap your output in a `Task.Run` so the gateway thread does not
- become blocked while waiting for logging data to be written.
