fn wrapping_div(self, rhs: u64) -> u64

Wrapping (modular) division. Computes self / other. Wrapped division on unsigned types is just normal division. There's no way wrapping could ever happen. This function exists, so that all operations are accounted for in the wrapping operations.

Examples

Basic usage:

assert_eq!(100u8.wrapping_div(10), 10);

fn wrapping_rem(self, rhs: u64) -> u64

Wrapping (modular) remainder. Computes self % other. Wrapped remainder calculation on unsigned types is just the regular remainder calculation. There's no way wrapping could ever happen. This function exists, so that all operations are accounted for in the wrapping operations.

Examples

Basic usage:

fn main() { assert_eq!(100u8.wrapping_rem(10), 0); }

assert_eq!(100u8.wrapping_rem(10), 0);

fn wrapping_neg(self) -> u64

Wrapping (modular) negation. Computes -self, wrapping around at the boundary of the type.

Since unsigned types do not have negative equivalents all applications of this function will wrap (except for -0). For values smaller than the corresponding signed type's maximum the result is the same as casting the corresponding signed value. Any larger values are equivalent to MAX + 1 - (val - MAX - 1) where MAX is the corresponding signed type's maximum.

Examples

Basic usage:

fn main() { assert_eq!(100u8.wrapping_neg(), 156); assert_eq!(0u8.wrapping_neg(), 0); assert_eq!(180u8.wrapping_neg(), 76); assert_eq!(180u8.wrapping_neg(), (127 + 1) - (180u8 - (127 + 1))); }

assert_eq!(100u8.wrapping_neg(), 156);
assert_eq!(0u8.wrapping_neg(), 0);
assert_eq!(180u8.wrapping_neg(), 76);
assert_eq!(180u8.wrapping_neg(), (127 + 1) - (180u8 - (127 + 1)));

fn wrapping_shl(self, rhs: u32) -> u64

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.

Examples

Basic usage:

fn main() { assert_eq!(1u8.wrapping_shl(7), 128); assert_eq!(1u8.wrapping_shl(8), 1); }

assert_eq!(1u8.wrapping_shl(7), 128);
assert_eq!(1u8.wrapping_shl(8), 1);

fn wrapping_shr(self, rhs: u32) -> u64

Panic-free bitwise shift-right; 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-right; the RHS of a wrapping shift-right 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_right function, which may be what you want instead.

Examples

Basic usage:

fn main() { assert_eq!(128u8.wrapping_shr(7), 1); assert_eq!(128u8.wrapping_shr(8), 128); }

assert_eq!(128u8.wrapping_shr(7), 1);
assert_eq!(128u8.wrapping_shr(8), 128);

fn overflowing_add(self, rhs: u64) -> (u64, bool)

Calculates self + rhs

Returns a tuple of the addition along with a boolean indicating whether an arithmetic overflow would occur. If an overflow would have occurred then the wrapped value is returned.

Examples

assert_eq!(5u32.overflowing_add(2), (7, false));
assert_eq!(u32::MAX.overflowing_add(1), (0, true));

fn overflowing_sub(self, rhs: u64) -> (u64, bool)

use std::u32;

assert_eq!(5u32.overflowing_sub(2), (3, false));

fn overflowing_mul(self, rhs: u64) -> (u64, bool)

assert_eq!(5u32.overflowing_mul(2), (10, false));
assert_eq!(1_000_000_000u32.overflowing_mul(10), (1410065408, true));

fn overflowing_div(self, rhs: u64) -> (u64, bool)

Calculates the divisor when self is divided by rhs.

Returns a tuple of the divisor along with a boolean indicating whether an arithmetic overflow would occur. Note that for unsigned integers overflow never occurs, so the second value is always false.

assert_eq!(0u32.overflowing_neg(), (0, false));
assert_eq!(2u32.overflowing_neg(), (-2i32 as u32, true));

fn overflowing_shl(self, rhs: u32) -> (u64, bool)

Shifts self left by rhs bits.

Returns a tuple of the shifted version of self along with a boolean indicating whether the shift value was larger than or equal to the number of bits. If the shift value is too large, then value is masked (N-1) where N is the number of bits, and this value is then used to perform the shift.
