    println!("{}", str.split(|e| e == '-').collect::<Vec<_>>());

}

error[E0277]: `Vec<&str>` doesn't implement `std::fmt::Display`
 --> src\main.rs:5:20
  |
5 |     println!("{}", str.split(|e| e == '-').collect::<Vec<_>>()); // ["aaa", "bbb", "ccc"]
  |                    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ `Vec<&str>` cannot be formatted with the default formatter

  = help: the trait `std::fmt::Display` is not implemented for `Vec<&str>`
  = note: in format strings you may be able to use `{:?}` (or {:#?} for pretty-print) instead
  = note: this error originates in the macro `$crate::format_args_nl` (in Nightly builds, run with -Z macro-backtrace for more info)

For more information about this error, try `rustc --explain E0277`.
