Struct Title 

pub struct Title { /* private fields */ }

How a terminal’s window title is taken, and given back.

One value carrying both halves, which is the entire point of the type. A title is a piece of the reader’s terminal that this run borrows, and the rule for everything borrowed here is that it has to be returnable. No terminal will tell an application what its title currently is — there is no query to ask — so the only way to put one back is to have asked the terminal to remember it first, which is what xterm’s title stack is for.

A terminal with no stack ignores the push, ignores the pop, and keeps whatever this run last set: pristine — freed 41.2 GiB in a tab bar for the rest of that terminal’s life. That is not a decoration degrading to nothing, it is a decoration that never leaves. So the two sequences are held together as one capability, and a terminal that is not known to have it is never sent a title at all — the setting cannot be switched on without the putting back.
