Implementations

impl Integer

pub fn is_signed(&self) -> bool

Returns true if the integer is signed, otherwise false

pub fn size(&self) -> usize

pub fn bits(&self) -> usize

Returns size of integer type in bits.

pub fn can_hold(&self, other: Integer) -> bool

Returns true if the integer is at least the same size (or larger) than other

pub fn fits(&self, num: BigInt) -> bool

Returns true if num represents a number that fits the type

pub fn max_value(&self) -> BigInt

Returns max value of the integer type.

pub fn min_value(&self) -> BigInt

Returns min value of the integer type.

Trait Implementations

impl AsRef<str> for Integer

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for Integer

fn clone(&self) -> Integer

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Integer

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

Formats the value using the given formatter.

impl Display for Integer

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

Formats the value using the given formatter.

impl FromStr for Integer

type Err = ParseError

The associated error which can be returned from parsing.

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

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

impl Hash for Integer

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl IntoEnumIterator for Integer

type Iterator = IntegerIter

fn iter() -> IntegerIter

impl Ord for Integer

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

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Integer

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for Integer

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl TryFrom<&str> for Integer

type Error = ParseError

The type returned in the event of a conversion error.

fn try_from(s: &str) -> Result<Integer, <Self as TryFrom<&str>>::Error>

Performs the conversion.

impl Copy for Integer

impl Eq for Integer

impl StructuralPartialEq for Integer
