Struct Int 

pub struct Int<const N: usize>(/* private fields */);

Generic Signed integer type composed of 64-bit digits, of arbitrary fixed size which must be known at compile time.

Digits are stored in little endian (the least significant digit first). This integer type aims to exactly replicate the behaviours of Rust’s built-in signed integer types: u8, u16, u32, u64, u128 and usize. The const generic parameter N is the number of 64-bit digits that are stored.

See also: https://doc.rust-lang.org/std/primitive.i64.html#method.div_ceil.

pub const fn bits(&self) -> u32

Returns the smallest number of bits necessary to represent self.

This is equal to the size of the type in bits minus the leading zeros of self.

Examples

Please note that this example is shared between integer types. Which explains why I256 is used here.

use fastnum::*;

assert_eq!(i256!(0b1111001010100).bits(), 13);
assert_eq!(I256::ZERO.bits(), 0);

pub const fn bit(&self, b: u32) -> bool

Returns a boolean representing the bit in the given position (true if the bit is set).

The least significant bit is at index 0, the most significant bit is at index Self::BITS - 1.

Examples

Please note that this example is shared between integer types. Which explains why I256 is used here.

use fastnum::*;

let n = i256!(0b001010100101010101);
assert!(n.bit(0));
assert!(!n.bit(1));
assert!(!n.bit(I256::BITS - 1));

impl<const N: usize> Int<N>

pub const fn mul(self, rhs: Self) -> Self

Performs the * operation.

pub const fn div(self, rhs: Self) -> Self

Performs the / operation.

pub const fn neg(self) -> Self

Performs the unary - operation.

pub const fn from_bits(bits: UInt<N>) -> Self

Creates an integer with bits as its underlying representation in two’s complement.

pub const fn to_bits(self) -> UInt<N>

This simply returns the underlying representation of the integer in two’s complement, as an unsigned integer.

pub const fn cast_unsigned(self) -> UInt<N>

Returns the bit pattern of self reinterpreted as an unsigned integer of the same size.

This produces the same result as an as cast, but ensures that the bit-width remains the same.

See also: https://doc.rust-lang.org/std/primitive.i64.html#method.cast_unsigned.

Examples

Please note that this example is shared between integer types. Which explains why I256 is used here.

use fastnum::*;

let a = i256!(-1);

assert_eq!(a.cast_unsigned(), U256::MAX);

pub const fn unsigned_abs(self) -> UInt<N>

Computes the absolute value of self as unsigned integer without panicking.let a = i256!(-50); let b = u256!(50);

See also: https://doc.rust-lang.org/std/primitive.i64.html#method.unsigned_abs.

pub const fn abs(self) -> Self

Computes the absolute value of self.

Overflow behavior

The absolute value of i128::MIN cannot be represented as an i128, and attempting to calculate it will cause an overflow. This means that code in debug mode will trigger a panic on this case and optimized code will return i128::MIN without a panic. If you do not want this behavior, consider using unsigned_abs instead.

let a = i256!(-50); let b = i256!(50);

assert_eq!(a.abs(), b);

See also: https://doc.rust-lang.org/std/primitive.i64.html#method.abs.

assert_eq!(i256!(0).signum(), i256!(0));
