Enum ValidationError 

#[non_exhaustive]
pub enum ValidationError {
    EmptyDomain,
    InvalidDomain {
        value: String,
        problem: &'static str,
    },
    InvalidEmail {
        value: String,
        problem: &'static str,
    },
    WithheldEmail {
        value: String,
    },
    RedactedEmail {
        value: String,
    },
}

A value that cannot be used as a query or as a result.

These come from the constructors of the newtypes in this crate. A lookup that is certain to fail never reaches the network, and a placeholder a registry sends in place of a real address never reaches the caller.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

EmptyDomain

The domain name was empty.

InvalidDomain

The domain name was not shaped like a domain name.

Fields

value: String

The rejected value.

problem: &'static str

What is wrong with it.

InvalidEmail

The email address was not shaped like an email address.

Fields

value: String

The rejected value.

problem: &'static str

What is wrong with it.

WithheldEmail

A source sent a fixed address that stands for “no contact published”.

A regional registry that withholds the contact of a network answers with one address for every network in the region. The address is a marker, not a mailbox that reads reports.

Fields

value: String

The marker the source sent.

RedactedEmail

The registry sent a placeholder in place of an address.

A registry that hides contact data puts a fixed string such as DATA REDACTED in the field. The string is not an address and must not be used as one.

Fields

value: String

The placeholder the registry sent.

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, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for ValidationError

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 Error

fn from(source: ValidationError) -> Self

Converts to this type from the input type.

impl PartialEq for ValidationError

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

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
