Implementations

impl NHSNumber

pub fn new(digits: [i8; 10]) -> Self

Create a new NHS Number instance with the provided digits.

pub fn check_digit(&self) -> i8

pub fn calculate_check_digit(&self) -> i8

pub fn validate_check_digit(&self) -> bool

Validate the NHS Number check digit equals the calculated check digit.

pub fn testable_random_sample() -> NHSNumber

Validate the NHS Number check digit equals the calculated check digit.

Trait Implementations

impl Clone for NHSNumber

fn clone(&self) -> NHSNumber

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NHSNumber

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for NHSNumber

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for NHSNumber

Format the NHS Number is a 10-digit number with spaces:

• 3 digits
• space
• 3 digits
• space
• 4 digits

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

Formats the value using the given formatter.

impl FromStr for NHSNumber

Implement the FromStr trait for NHSNumber to allow parsing from a string.

This parser allows for optional spcae separators in the NHS Number string, so long as the space separators are in their expected positions.

type Err = ParseError

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 Ord for NHSNumber

fn cmp(&self, other: &NHSNumber) -> 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 NHSNumber

fn eq(&self, other: &NHSNumber) -> 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 NHSNumber

fn partial_cmp(&self, other: &NHSNumber) -> 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 Serialize for NHSNumber

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
