Basic usage:
1.2.0 (const: 1.32.0) · sourcepub const fn wrapping_shl(self, rhs: u32) -> i8
pub const fn wrapping_shl(self, rhs: u32) -> i8
Panic-free bitwise shift-left; yields self << mask(rhs)
, where mask
removes
any high-order bits of rhs
that would cause the shift to exceed the bitwidth of the type.
Note that this is not the same as a rotate-left; the RHS of a wrapping shift-left is restricted to
the range of the type, rather than the bits shifted out of the LHS being returned to the other end.
The primitive integer types all implement a rotate_left
function,
which may be what you want instead.

pub const fn wrapping_abs(self) -> i8
Wrapping (modular) absolute value. Computes self.abs()
, wrapping around at
the boundary of the type.
The only case where such wrapping can occur is when one takes the absolute value of the negative
minimal value for the type; this is a positive value that is too large to represent in the type. In
such a case, this function returns MIN
itself.

and checks for overflow.
Performs “ternary addition” of two integer operands and a carry-in bit, and returns a tuple of the sum along with a boolean indicating whether an arithmetic overflow would occur. On overflow, the wrapped value is returned.
This allows chaining together multiple additions to create a wider
addition, and can be useful for bignum addition. This method should
only be used for the most significant word; for the less significant
words the unsigned method

The output boolean returned by this method is not a carry flag, and should not be added to a more significant word.
If the input carry is false, this method is equivalent to

if self < 0
, this is equal to rounding away from zero (towards +/- infinity).
If rhs > 0
, this is equal to rounding towards -infinity;
if rhs < 0
, this is equal to rounding towards +infinity.
