```
server.Server.from_env_value(value: Option<impl Into<OsString>>) -> Result<Self, Error>
```

Build a server from an explicit `TMUX` value.

This resolves on behalf of another pane, or in a test, without touching
the process environment.

# Errors

Returns an error when the value is absent, empty, or not shaped like
tmux's triple, and when the socket path it names is unusable.
