# Type Definition futures_util::never::Never [−] [src]

    type Never = Infallible;

A type with no possible values.

This is used to indicate values which can never be created, such as the error type of infallible futures.

This type is a stable equivalent to the `!` type from `std`.

This is currently an alias for [`std::convert::Infallible`], but in the future it may be an alias for `!`. See “Future compatibility” section of `std::convert::Infallible` for more.
