Variants

Empty

Input is empty or whitespace-only.

MissingAtSign

Missing @ separator.

EmptyLocalPart

Local part is empty (nothing before @).

EmptyDomain

Domain is empty (nothing after @).

LocalPartTooLong

Local part exceeds 64 octets (RFC 5321 §4.5.3.1.1).

Fields

len: usize

AddressTooLong

Total address exceeds 254 octets (RFC 5321 §4.5.3.1.3).

Fields

len: usize

DomainLabelTooLong

Domain label exceeds 63 octets (RFC 1035 §2.3.4).

Fields

label: String

len: usize

InvalidLocalPartChar

Invalid character in local part.

Fields

ch: char

InvalidDomainChar

Invalid character in domain.

Fields

ch: char

DomainLabelHyphen

Domain label starts or ends with hyphen.

DomainNoDot

Domain has no dot (single label, not a valid internet domain).

UnterminatedQuotedString

Unterminated quoted string.

InvalidQuotedPair

Invalid quoted-pair sequence.

UnterminatedComment

Unterminated comment.

UnterminatedDomainLiteral

Unterminated domain literal [...].

InvalidAddressLiteral

Domain literal [...] is not a valid IPv4 or IPv6: address literal (RFC 5321 §4.1.3). General domain literals are not accepted.

IdnaError(String)

IDNA encoding failed for domain.

UnknownTld(String)

Domain not in Public Suffix List (when PSL validation enabled).

Unexpected

Generic parse failure at position.

Fields

ch: char

Trait Implementations

impl Clone for ErrorKind

fn clone(&self) -> ErrorKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ErrorKind

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

Formats the value using the given formatter.

impl Eq for ErrorKind

impl PartialEq for ErrorKind

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