Enum ValidationError 

pub enum ValidationError {
    Empty,
    WrongLength {
        expected: usize,
        found: usize,
    },
    InvalidCharacter {
        position: usize,
        found: char,
    },
    BadCheckDigit {
        expected: char,
        found: char,
    },
    InvalidCountryCode,
    Structure {
        rule: &'static str,
    },
}

Error returned when a string is not a well-formed securities identifier.

Every identifier type has a strict grammar: an exact length (or a small set of lengths), a per-segment character set, and — for most — a check digit. A parse or validate call returns one of these variants the moment an input violates that grammar.

Examples

use regit_identifiers::errors::ValidationError;

let err = ValidationError::WrongLength { expected: 12, found: 11 };
assert_eq!(err, ValidationError::WrongLength { expected: 12, found: 11 });

Variants

Empty

The input string was empty.

WrongLength

The input has the wrong length for this identifier.

Fields

expected: usize

The length the identifier requires.

found: usize

The length that was supplied.

InvalidCharacter

The character at 1-based position is not allowed there.

Fields

position: usize

The 1-based index of the offending character.

found: char

The offending character.

BadCheckDigit

The recomputed check digit did not match the supplied one.

For multi-digit schemes (LEI) this reports the first differing digit.

Fields

expected: char

The check digit the algorithm computed.

found: char

The check digit that was supplied.

InvalidCountryCode

The country-code segment is not a recognised code.

Structure

A structural rule of the identifier was violated; rule names it.

Fields

rule: &'static str

A short, human-readable description of the violated rule.

Trait Implementations

impl Clone for ValidationError

fn clone(&self) -> ValidationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ValidationError

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

Formats the value using the given formatter.

impl Display for ValidationError

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

Formats the value using the given formatter.

impl Error for ValidationError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<ValidationError> for ConversionError

fn from(e: ValidationError) -> Self

Converts to this type from the input type.

impl PartialEq for ValidationError

fn eq(&self, other: &ValidationError) -> 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 Copy for ValidationError

impl Eq for ValidationError

impl StructuralPartialEq for ValidationError
