error[E0373]: closure may outlive the current function, but it borrows `out`, which is owned by the current function     --> src/main.rs:6:34

  |                                  ^^^^^ --- `out` is borrowed here

note: closure is returned here

  |                                  ^^^^^^^^^^^^^^^^^^^
help: to force the closure to take ownership of `out` (and any other referenced variables), use the `move` keyword        |
6 |   listen("127.0.0.1:8888", |out| move |msg| out.send(msg)).unwrap()
  |                                  ^^^^^^^^^^
