```
libtmux::Server::session(target: std::string_view) -> expected< Session, CommandFailure >
```

One object by target, for a caller holding an id or a `session:window` path that came from somewhere else.

The target is resolved the way tmux resolves it, so a session target names that session's active pane and the window that pane is in. A target tmux cannot resolve is reported missing.
