Can we please deprecate the "as" operator? Something so lossy and ill-conceived should not be a two-letter operator.

  It is possible, someone needs to do the RFC work. I would say that my personal take of the temperature is "vaguely pro but not a slam dunk", at least from the opinions I've seen. Only one way to find out.

  Then what do you propose for replacement? C++ style casts `(int) x` ?
  • erk__ 6y ago
    Using `x.into()` instead or `x.try_into()` if it can fail.
  • devit 6y ago
    into()/try_into() and methods designed for each of the other cases (e.g. truncate(), saturating_to_int(), approx_to_float(), etc.)
• stefano_c 6y ago
  What would you suggest for replacing e.g. `u8 as usize`?
  • steveklabnik 6y ago
    For this one, you could use From/Into, because it cannot fail. For numerics that can fail, TryFrom/TryInto. The numeric casts are the easy part of this.
