server.settings.Server.environment

environment ( self , name : &str ) → Result<Option<EnvironmentEntry>, Error> method [source] ¶ method [source] ¶ environment: Read one variable from the server's environment.

tmux keeps two different things under a name: a value, and a mark saying a process started from it must not inherit the name at all. [ EnvironmentEntry ] keeps them apart, because collapsing both to absence would hide the second, which a caller sets deliberately with Self::hide_environment.
None means tmux holds nothing under the name.
Errors
