Struct NonNegativeNumber 

pub struct NonNegativeNumber {
    string: String,
    value: usize,
}

A number string guaranteed to be non-negative.

Fields

string: String

The string representation of the non-negative number.

value: usize

The numeric value of the non-negative number.

Implementations

impl NonNegativeNumber

pub fn string(&self) -> &str

Returns the string representation of the non-negative number.

pub fn value(&self) -> usize

Returns the numeric value of the non-negative number.

pub fn is_zero(&self) -> bool

Returns true if this number is zero.

Trait Implementations

impl Clone for NonNegativeNumber

fn clone(&self) -> NonNegativeNumber

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NonNegativeNumber

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for NonNegativeNumber

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for NonNegativeNumber

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

Formats the value using the given formatter.

impl From<String> for NonNegativeNumber

fn from(string: String) -> Self

Converts to this type from the input type.

impl From<usize> for NonNegativeNumber

fn from(value: usize) -> Self

Converts to this type from the input type.

impl Hash for NonNegativeNumber

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 PartialEq for NonNegativeNumber

fn eq(&self, other: &NonNegativeNumber) -> 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 Serialize for NonNegativeNumber

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
