Type Alias sp_arithmetic::biguint::Double

pub type Double = u64;

Representation of two limbs.

Trait Implementations

impl Bounded for u64

fn min_value() -> u64

Returns the smallest finite number this type can represent

fn max_value() -> u64

Returns the largest finite number this type can represent

impl CheckedAdd for u64

fn checked_add(&self, v: &u64) -> Option<u64>

Adds two numbers, checking for overflow. If overflow happens, None is returned.

impl CheckedDiv for u64

fn checked_div(&self, v: &u64) -> Option<u64>

Divides two numbers, checking for underflow, overflow and division by zero. If any of that happens, None is returned.

impl CheckedMul for u64

fn checked_mul(&self, v: &u64) -> Option<u64>

Multiplies two numbers, checking for underflow or overflow. If underflow or overflow happens, None is returned.

impl CheckedNeg for u64

fn checked_neg(&self) -> Option<u64>

Negates a number, returning None for results that can’t be represented, like signed MIN values that can’t be positive, or non-zero unsigned values that can’t be negative.

impl CheckedRem for u64

fn checked_rem(&self, v: &u64) -> Option<u64>

Finds the remainder of dividing two numbers, checking for underflow, overflow and division by zero. If any of that happens, None is returned.

impl CheckedShl for u64

fn checked_shl(&self, rhs: u32) -> Option<u64>

Checked shift left. Computes self << rhs, returning None if rhs is larger than or equal to the number of bits in self.

impl CheckedShr for u64

fn checked_shr(&self, rhs: u32) -> Option<u64>

Checked shift right. Computes self >> rhs, returning None if rhs is larger than or equal to the number of bits in self.

impl CheckedSub for u64

fn checked_sub(&self, v: &u64) -> Option<u64>

Subtracts two numbers, checking for underflow. If underflow happens, None is returned.

impl MultiplyRational for u64

fn multiply_rational(self, n: Self, d: Self, r: Rounding) -> Option<Self>

impl One for u64

fn one() -> u64

Returns the multiplicative identity element of Self, 1.

fn is_one(&self) -> bool

Returns true if self is equal to the multiplicative identity.

fn set_one(&mut self)

Sets self to the multiplicative identity element of Self, 1.

impl TryFrom<BigUint> for u64

type Error = &'static str

The type returned in the event of a conversion error.

fn try_from(value: BigUint) -> Result<u64, Self::Error>

Performs the conversion.

impl Zero for u64

fn zero() -> u64

Returns the additive identity element of Self, 0.

fn is_zero(&self) -> bool

Returns true if self is equal to the additive identity.

fn set_zero(&mut self)

Sets self to the additive identity element of Self, 0.

impl Unsigned for u64
