Struct ParseError 

pub struct ParseError;

Error returned by <NHSNumber as FromStr>::from_str for any string that is not one of the two accepted shapes (see spec.md §5).

ParseError is a unit struct — every error value compares equal:

use nhs_number::NHSNumber;
use nhs_number::parse_error::ParseError;
use std::str::FromStr;

let a = NHSNumber::from_str("not even close").unwrap_err();
let b = NHSNumber::from_str("wrong length").unwrap_err();
assert_eq!(a, b);
assert_eq!(a, ParseError);

To map it to your own richer error type:

use nhs_number::NHSNumber;
use std::str::FromStr;

#[derive(Debug, PartialEq)]
enum MyError {
    BadNhsNumber(String),
}

let bad = "not a number";
let result: Result<NHSNumber, MyError> =
    NHSNumber::from_str(bad).map_err(|_| MyError::BadNhsNumber(bad.into()));
assert_eq!(result, Err(MyError::BadNhsNumber("not a number".into())));

Trait Implementations

impl Debug for ParseError

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

Formats the value using the given formatter.

impl Eq for ParseError

impl PartialEq for ParseError

fn eq(&self, other: &ParseError) -> 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.
