Overview

An informational firehose message from the websocket service itself, unrelated to any repos.

Currently there is only one type of message defined, ‘“OutdatedCursor”`, which is sent when the client connects with a cursor that is older than the oldest event currently kept in the backfill buffer. This message means that you’re likely missing some events that were sent since the last time the client was connected but which were already deleted from the buffer.

Note: the Message#did, Message#seq and Message#time properties are always nil for #info messages.
