Struct codes_check_digits::sedol::CheckDigitAlgorithm

pub struct CheckDigitAlgorithm {}

Validate the SEDOL numbers defined by the London Stock Exchange

Trait Implementations

impl Calculator<u8> for CheckDigitAlgorithm

fn name(&self) -> &'static str

Return the name of this algorithm.

fn calculate(&self, s: &str) -> Result<u8, CheckDigitError>

Calculate a check digit for the provided string.

fn number_of_check_digit_chars(&self) -> usize

Return the number of characters used as the check digit. Currently it is assumed that these are the n right-most characters in the input string.

fn create(&self, s: &str) -> Result<String, CheckDigitError>

Create a new string with the original data plus check digit.

fn validate<S>(&self, s: S) -> Result<(), CheckDigitError>where
    S: AsRef<str>,

Validate that the string is valid and that it contains a valid check digit.

fn is_valid<S>(&self, s: S) -> boolwhere
    S: AsRef<str>,

Returns true if the provided string includes a valid check digit, else false. The default implementation relies on the validate method.

impl Debug for CheckDigitAlgorithm

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

Formats the value using the given formatter.

impl Default for CheckDigitAlgorithm

fn default() -> CheckDigitAlgorithm

Returns the “default value” for a type.
