Error type for email validation.

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.

Empty

Empty email

The provided string is empty. Email addresses must contain at least one character.

TooLong(usize)

Email exceeds maximum length of 254 characters

According to RFC 5321, email addresses must not exceed 254 characters. This variant contains the actual length of the provided email.

MissingAtSymbol

Missing @ symbol

Email addresses must contain exactly one @ symbol separating the local and domain parts.

MultipleAtSymbols

Multiple @ symbols

Email addresses must contain exactly one @ symbol.

EmptyLocalPart

Empty local part

The local part (before @) is empty.

EmptyDomain

Empty domain part

The domain part (after @) is empty.

LocalPartTooLong(usize)

Local part exceeds maximum length of 64 characters

According to RFC 5321, the local part must not exceed 64 characters. This variant contains the actual length of the local part.

InvalidLocalPartChar(char)

Invalid character in local part The local part contains an invalid character. This variant contains the invalid character.

LocalPartStartsWithDot

Local part starts with a dot

The local part cannot start with a dot.

LocalPartEndsWithDot

Local part ends with a dot

The local part cannot end with a dot.

LocalPartConsecutiveDots

Local part contains consecutive dots

The local part cannot contain consecutive dots.

InvalidDomain

Invalid domain part

The domain part is invalid according to RFC 1035. This variant contains the domain validation error.

Trait Implementations

impl Clone for EmailError

fn clone(&self) -> EmailError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EmailError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for EmailError

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for EmailError

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

Formats the value using the given formatter.

impl Error for EmailError

Available on crate feature std only.

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 PartialEq for EmailError

fn eq(&self, other: &EmailError) -> 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 Serialize for EmailError

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
