Enum ValidationResult 

pub enum ValidationResult {
    Valid,
    InvalidLength {
        expected: usize,
        actual: usize,
    },
    InvalidCharacter {
        char: char,
        position: usize,
    },
    InvalidCheckDigit,
    InvalidFormat {
        reason: String,
    },
}

Validation result with detailed information.

This enum provides specific information about why a code validation succeeded or failed, useful for user feedback.

Variants

Valid

Code is valid (format check passed).

InvalidLength

Code has wrong length.

Fields

expected: usize

Expected code length.

actual: usize

Actual code length.

InvalidCharacter

Code contains character not in alphabet.

Fields

char: char

The invalid character found.

position: usize

Position of the invalid character (0-indexed).

InvalidCheckDigit

Check digit verification failed.

InvalidFormat

Format mismatch (prefix/suffix/separator).

Fields

reason: String

Description of what was wrong with the format.

Implementations

impl ValidationResult

pub fn is_valid(&self) -> bool

Returns true if the validation result indicates a valid code.

pub fn error_code(&self) -> u8

Returns the error code for FFI compatibility.

pub fn error_position(&self) -> i32

Returns the error position for character errors, or -1 if not applicable.

pub fn error_char(&self) -> char

Returns the invalid character, or ‘\0’ if not applicable.

Trait Implementations

impl Clone for ValidationResult

fn clone(&self) -> ValidationResult

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ValidationResult

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

Formats the value using the given formatter.

impl PartialEq for ValidationResult

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