control.ControlSender.watch_only

watch_only ( self , panes : &[PaneId] ) → Result<(), Error> method [source] ¶ method [source] ¶ watch_only: Receive output from these panes and no others.

Lists panes over this same connection, so the answer cannot disagree with the connection it configures, then mutes every pane not named. See Self::mute_pane for why this beats filtering what arrives.
A pane created after this call is not muted, because tmux publishes no notification for a pane appearing. Repeat this whenever Event::may_have_added_a_pane answers true.
Errors
Returns an error when the connection has closed, tmux would not list a pane, returned an unreadable pane ID, or a later mute fails. A failure after an accepted mute is Error::AfterEffect .
