Enum UrnValidationError 

pub enum UrnValidationError {
    RequiredFieldMissing(&'static str),
    InvalidFormat {
        field: &'static str,
        pattern: Option<Pattern>,
    },
    ForbiddenFieldPresent(&'static str),
    NidMismatch,
    InvalidNidLength,
    InvalidNidStart,
    InvalidNidCharacters,
}

Errors that can occur during URN validation and construction

Variants

RequiredFieldMissing(&'static str)

A required field is missing

InvalidFormat

A field has an invalid format

Fields

field: &'static str

pattern: Option<Pattern>

ForbiddenFieldPresent(&'static str)

A forbidden field is present

NidMismatch

NID does not match the spec’s expected NID

InvalidNidLength

NID length is invalid (must be 2-32 characters)

InvalidNidStart

NID must start with a letter

InvalidNidCharacters

NID contains invalid characters (must be alphanumeric and hyphens only)

Trait Implementations

impl Clone for UrnValidationError

fn clone(&self) -> UrnValidationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UrnValidationError

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

Formats the value using the given formatter.

impl Display for UrnValidationError

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

Formats the value using the given formatter.

impl Error for UrnValidationError

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<TightBeamError> for UrnValidationError

fn from(err: TightBeamError) -> Self

Converts to this type from the input type.

impl From<UrnValidationError> for TightBeamError

fn from(err: UrnValidationError) -> Self

Converts to this type from the input type.

impl PartialEq for UrnValidationError

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