error[E0621]: explicit lifetime required in the type of `x`

error[E0373]: closure may outlive the current function, but it borrows `x`, which is owned by the current function

note: function requires argument type to outlive `'static`

help: to force the closure to take ownership of `x` (and any other referenced variables), use the `move` keyword
