That's not all it does. It "breaks" to the nearest "try" barrier. It's basically the desugaring of the Err branch in the ? operator, that you can't currently express yourself. It's mostly relevant for try blocks. I guess you'd most commonly see this in "control flow like" macros that are similar to the ? operator, like various assertion macros that want to "yeet" an error in case the assertion fails (instead of panicking like those in std). So in a sense it actually is very similar to `throw` in traditional languages, as it can be caught inside the same function and isn't forced to `return` the error outside the function.
