Description

u32 and other primitive integer types implement a number of bit-manipulation methods like rotate_left, but Wrapping<_> does not. At the moment this can be worked around with code like Wrapping(x.0.rotate_left(n)) instead of x.rotate_left(n).

It would be nice to implement:

• count_ones
• count_zeroes
• leading_zeroes
• trailing_zeroes
• rotate_left
• rotate_right
• swap_bytes
• from_be (?)
• from_le (?)
• to_be
• to_le
• pow (?)

Edit: Others added after #32463 (comment)

• is_power_of_two (?)
• next_power_of_two (?)
• min_value (?)
• max_value (?)
• from_str_radix (?)
• reverse_bits
• abs Add missing Wrapping methods, use doc_comment! #49393 Add missing Wrapping methods, use doc_comment! #50465
• signum Add missing Wrapping methods, use doc_comment! #49393 Add missing Wrapping methods, use doc_comment! #50465

• is_negative Add missing Wrapping methods, use doc_comment! #49393 Add missing Wrapping methods, use doc_comment! #50465

and maybe other methods, for:

• Wrapping<u8>
• Wrapping<u16>
• Wrapping<u32>
• Wrapping<u64>
• Wrapping<usize>
• Wrapping<i8>
• Wrapping<i16>
• Wrapping<i32>
• Wrapping<i64>
• Wrapping<isize>

Edit: From #50465

• Decide on correct behavior for wrapping_next_power_of_two
