Enum CustomValidationResult 

pub enum CustomValidationResult {
    Valid,
    Invalid {
        constraint: String,
        reason: String,
    },
}

Result of a custom validation function

Variants

Valid

Validation passed

Invalid

Validation failed with a specific constraint name and reason

Fields

constraint: String

Name of the constraint that failed (e.g., “email_format”, “port_range”)

reason: String

Human-readable reason for failure

Implementations

impl CustomValidationResult

pub fn invalid(constraint: impl Into<String>, reason: impl Into<String>) -> Self

Create a validation failure

pub fn is_valid(&self) -> bool

Check if validation passed

pub fn is_invalid(&self) -> bool

Check if validation failed

Trait Implementations

impl Clone for CustomValidationResult

fn clone(&self) -> CustomValidationResult

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CustomValidationResult

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

Formats the value using the given formatter.

impl PartialEq for CustomValidationResult

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