Struct subgraph::num::BigInt

pub struct BigInt { /* private fields */ }

A arbitrarily sized integer type.

Implementations

impl BigInt

pub fn new(x: i128) -> Self

Creates a new big integer.

pub fn from_signed_bytes_le(bytes: impl AsRef<[u8]>) -> Self

Creates a new big integer value from it signed little-endian reprensentation. Unsigned integers need to ensure that the most significant bit is not set.

pub fn signum(&self) -> i32

Returns the sign of the integer.

pub fn parse(s: impl AsRef<str>) -> Self

Parses a big integer from a string.

pub fn plus(&self, rhs: &Self) -> Self

Returns the sum of two big integers.

pub fn minus(&self, rhs: &Self) -> Self

Returns the difference of two big integers.

pub fn times(&self, rhs: &Self) -> Self

Returns the product of two big integers.

pub fn divided_by(&self, rhs: &Self) -> Self

Returns the division of two big integers.

pub fn divided_by_decimal(&self, rhs: &BigDecimal) -> BigDecimal

Returns the division of a big integer by a big decimal.

pub fn rem(&self, rhs: &Self) -> Self

Returns the remainder of two big integers.

pub fn pow(&self, exp: u8) -> Self

function pow(x: BigInt, exp: u8): BigInt

pub fn bit_or(&self, rhs: &Self) -> Self

Returns the bit-wise or of two big integers.

pub fn bit_and(&self, rhs: &Self) -> Self

Returns the bit-wise and of two big integers.

pub fn left_shift(&self, rhs: u8) -> Self

Returns the left shift by rhs bits.

pub fn right_shift(&self, rhs: u8) -> Self

Returns the arithmetic right shift by rhs bits.

Trait Implementations

impl Clone for BigInt

fn clone(&self) -> BigInt

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BigInt

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for BigInt

fn default() -> Self

Returns the “default value” for a type.

impl Display for BigInt

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl FromStr for BigInt

type Err = Infallible

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl LowerHex for BigInt

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Ord for BigInt

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<BigInt> for BigInt

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd<BigInt> for BigInt

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl UpperHex for BigInt

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
