🔬This is a nightly-only experimental API. (strict_overflow_ops #118260)

Strict integer addition. Computes self + rhs, panicking if overflow occurred.

Panics

Overflow behavior

This function will always panic on overflow, regardless of whether overflow checks are enabled.

Examples

Basic usage:

#![feature(strict_overflow_ops)]
assert_eq!((u64::MAX - 2).strict_add(1), u64::MAX - 1);

The following panics because of overflow:

#![feature(strict_overflow_ops)]
let _ = (u64::MAX - 2).strict_add(3);

pub const unsafe fn unchecked_add(self, rhs: u64) -> u64

Unchecked integer addition. Computes self + rhs, assuming overflow cannot occur.

Calling x.unchecked_add(y) is semantically equivalent to calling x.checked_add(y).unwrap_unchecked().

If you’re just trying to avoid the panic in debug mode, then do not use this. Instead, you’re looking for wrapping_add.

Safety

This results in undefined behavior when self + rhs > u64::MAX or self + rhs < u64::MIN, i.e. when checked_add would return None.

pub const fn checked_add_signed(self, rhs: i64) -> Option<u64>

Checked addition with a signed integer. Computes self + rhs, returning None if overflow occurred.

Examples

Basic usage:

The following panic because of overflow:

#![feature(strict_overflow_ops)]
let _ = 1u64.strict_add_signed(-2);

#![feature(strict_overflow_ops)]
let _ = (u64::MAX - 2).strict_add_signed(3);

pub const fn checked_sub(self, rhs: u64) -> Option<u64>

Panics

Overflow behavior

Examples

Basic usage:

#![feature(strict_overflow_ops)]
assert_eq!(1u64.strict_sub(1), 0);

The following panics because of overflow:

#![feature(strict_overflow_ops)]
let _ = 0u64.strict_sub(1);

pub const unsafe fn unchecked_sub(self, rhs: u64) -> u64

Unchecked integer subtraction. Computes self - rhs, assuming overflow cannot occur.

Calling x.unchecked_sub(y) is semantically equivalent to calling x.checked_sub(y).unwrap_unchecked().

If you’re just trying to avoid the panic in debug mode, then do not use this. Instead, you’re looking for wrapping_sub.

If you find yourself writing code like this:

if foo >= bar {
    // SAFETY: just checked it will not overflow
    let diff = unsafe { foo.unchecked_sub(bar) };
    // ... use diff ...
}

Consider changing it to

if let Some(diff) = foo.checked_sub(bar) {
    // ... use diff ...
}

As that does exactly the same thing – including telling the optimizer that the subtraction cannot overflow – but avoids needing unsafe.

Safety

This results in undefined behavior when self - rhs > u64::MAX or self - rhs < u64::MIN, i.e. when checked_sub would return None.

Since, for the positive integers, all common definitions of division are equal, this is exactly equal to self.wrapping_div(rhs).

pub const 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

pub const 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.

The primitive integer types all implement a rotate_left function, which may be what you want instead.

Calculates self + rhs + carry and returns a tuple containing the sum and the output carry.

Performs “ternary addition” of two integer operands and a carry-in bit, and returns an output integer and a carry-out bit. This allows chaining together multiple additions to create a wider addition, and can be useful for bignum addition.

This can be thought of as a 64-bit “full adder”, in the electronics sense.

If the input carry is false, this method is equivalent to overflowing_add, and the output carry is equal to the overflow flag. Note that although carry and overflow flags are similar for unsigned integers, they are different for signed integers.

Creates a native endian integer value from its memory representation as a byte array in native endianness.

As the target platform’s native endianness is used, portable code likely wants to use from_be_bytes or from_le_bytes, as appropriate instead.

Examples

let value = u64::from_ne_bytes(if cfg!(target_endian = "big") {
    [0x12, 0x34, 0x56, 0x78, 0x90, 0x12, 0x34, 0x56]
} else {
    [0x56, 0x34, 0x12, 0x90, 0x78, 0x56, 0x34, 0x12]
});
assert_eq!(value, 0x1234567890123456);

When starting from a slice rather than an array, fallible conversion APIs can be used:

fn read_ne_u64(input: &mut &[u8]) -> u64 {
    let (int_bytes, rest) = input.split_at(std::mem::size_of::<u64>());
    *input = rest;
    u64::from_ne_bytes(int_bytes.try_into().unwrap())
}

pub const fn min_value() -> u64

👎Deprecating in a future version: replaced by the MIN associated constant on this type

New code should prefer to use u64::MIN instead.

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

pub const fn max_value() -> u64

👎Deprecating in a future version: replaced by the MAX associated constant on this type

New code should prefer to use u64::MAX instead.

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

pub const fn widening_mul(self, rhs: u64) -> (u64, u64)

🔬This is a nightly-only experimental API. (bigint_helper_methods #85532)

Calculates the complete product self * rhs without the possibility to overflow.

This returns the low-order (wrapping) bits and the high-order (overflow) bits of the result as two separate values, in that order.

If you also need to add a carry to the wide result, then you want Self::carrying_mul instead.

Examples

Basic usage:

Please note that this example is shared between integer types. Which explains why u32 is used here.

#![feature(bigint_helper_methods)]
assert_eq!(5u32.widening_mul(2), (10, 0));
assert_eq!(1_000_000_000u32.widening_mul(10), (1410065408, 2));

pub const fn carrying_mul(self, rhs: u64, carry: u64) -> (u64, u64)

🔬This is a nightly-only experimental API. (bigint_helper_methods #85532)

Calculates the “full multiplication” self * rhs + carry without the possibility to overflow.

This returns the low-order (wrapping) bits and the high-order (overflow) bits of the result as two separate values, in that order.

Performs “long multiplication” which takes in an extra amount to add, and may return an additional amount of overflow. This allows for chaining together multiple multiplications to create “big integers” which represent larger values.

If you don’t need the carry, then you can use Self::widening_mul instead.

Examples

Basic usage:

Please note that this example is shared between integer types. Which explains why u32 is used here.

#![feature(bigint_helper_methods)]
assert_eq!(5u32.carrying_mul(2, 0), (10, 0));
assert_eq!(5u32.carrying_mul(2, 10), (20, 0));
assert_eq!(1_000_000_000u32.carrying_mul(10, 0), (1410065408, 2));
assert_eq!(1_000_000_000u32.carrying_mul(10, 10), (1410065418, 2));
assert_eq!(u64::MAX.carrying_mul(u64::MAX, u64::MAX), (0, u64::MAX));

This is the core operation needed for scalar multiplication when implementing it for wider-than-native types.

#![feature(bigint_helper_methods)]
fn scalar_mul_eq(little_endian_digits: &mut Vec<u16>, multiplicand: u16) {
    let mut carry = 0;
    for d in little_endian_digits.iter_mut() {
        (*d, carry) = d.carrying_mul(multiplicand, carry);
    }
    if carry != 0 {
        little_endian_digits.push(carry);
    }
}

let mut v = vec![10, 20];
scalar_mul_eq(&mut v, 3);
assert_eq!(v, [30, 60]);

assert_eq!(0x87654321_u64 * 0xFEED, 0x86D3D159E38D);
let mut v = vec![0x4321, 0x8765];
scalar_mul_eq(&mut v, 0xFEED);
assert_eq!(v, [0xE38D, 0xD159, 0x86D3]);

If carry is zero, this is similar to overflowing_mul, except that it gives the value of the overflow instead of just whether one happened:

#![feature(bigint_helper_methods)]
let r = u8::carrying_mul(7, 13, 0);
assert_eq!((r.0, r.1 != 0), u8::overflowing_mul(7, 13));
let r = u8::carrying_mul(13, 42, 0);
assert_eq!((r.0, r.1 != 0), u8::overflowing_mul(13, 42));

The value of the first field in the returned tuple matches what you’d get by combining the wrapping_mul and wrapping_add methods:

#![feature(bigint_helper_methods)]
assert_eq!(
    789_u16.carrying_mul(456, 123).0,
    789_u16.wrapping_mul(456).wrapping_add(123),
);

pub const fn midpoint(self, rhs: u64) -> u64

🔬This is a nightly-only experimental API. (num_midpoint #110840)

Calculates the middle point of self and rhs.

midpoint(a, b) is (a + b) >> 1 as if it were performed in a sufficiently-large signed integral type. This implies that the result is always rounded towards negative infinity and that no overflow will ever occur.

Examples

#![feature(num_midpoint)]
assert_eq!(0u64.midpoint(4), 2);
assert_eq!(1u64.midpoint(4), 2);

impl u64

pub const fn from_str_radix(src: &str, radix: u32) -> Result<u64, ParseIntError>

Converts a string slice in a given base to an integer.

The string is expected to be an optional + sign followed by only digits. Leading and trailing non-digit characters (including whitespace) represent an error. Underscores (which are accepted in rust literals) also represent an error.

Digits are a subset of these characters, depending on radix:

• 0-9
• a-z
• A-Z

Panics

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

Examples

Basic usage:

assert_eq!(u64::from_str_radix("A", 16), Ok(10));

Trailing space returns error:

assert!(u64::from_str_radix("1 ", 10).is_err());
