[src]

Returns the smallest value that can be represented by this integer type.

Examples

Basic usage:

assert_eq!(u64::min_value(), 0);Run

`pub const fn max_value() -> u64`
[src]

Returns the largest value that can be represented by this integer type.

0-9
a-z
A-Z

This function panics if radix is not in the range from 2 to 36.

[src]

Wrapping (modular) division. Computes self / rhs. 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.

`pub fn wrapping_rem(self, rhs: u64) -> u64`
1.2.0
[src]

Wrapping (modular) remainder. Computes self % rhs. 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:

assert_eq!(100u64.wrapping_rem(10), 0);Run

`pub fn wrapping_neg(self) -> u64`
1.2.0
[src]

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:

Please note that this example is shared between integer types. Which explains why i8 is used here.

assert_eq!(100i8.wrapping_neg(), -100);
assert_eq!((-128i8).wrapping_neg(), -128);Run

`pub fn wrapping_shl(self, rhs: u32) -> u64`
1.2.0
[src]

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:

assert_eq!(1u64.wrapping_shl(7), 128);
assert_eq!(1u64.wrapping_shl(128), 1);Run

`pub fn wrapping_shr(self, rhs: u32) -> u64`
1.2.0
[src]

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:

assert_eq!(128u64.wrapping_shr(7), 1);
assert_eq!(128u64.wrapping_shr(128), 128);Run

assert_eq!(3u8.wrapping_pow(6), 217);Run

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

`pub fn overflowing_div(self, rhs: u64) -> (u64, bool)`
1.7.0
[src]

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.

`pub fn overflowing_rem(self, rhs: u64) -> (u64, bool)`
1.7.0

`pub fn overflowing_neg(self) -> (u64, bool)`
1.7.0
[src]

assert_eq!(2u64.overflowing_neg(), (-2i32 as u64, true));Run

`pub fn overflowing_shl(self, rhs: u32) -> (u64, bool)`
1.7.0
[src]

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.

Examples

Basic usage

assert_eq!(0x1u64.overflowing_shl(4), (0x10, false));
assert_eq!(0x1u64.overflowing_shl(132), (0x10, true));Run

assert!(!10u64.is_power_of_two());Run

`pub fn next_power_of_two(self) -> u64`
[src]

Returns the smallest power of two greater than or equal to self.
