It's a [type alias] for an `extern "x86-interrupt" fn` type. The `extern` keyword defines a function with a [foreign calling convention] and is often used to communicate with C code (`extern "C" fn`). But what is the `x86-interrupt` calling convention?

Exceptions are quite similar to function calls: The CPU jumps to the first instruction of the called function and executes it. Afterwards the CPU jumps to the return address and continues the execution of the parent function.
