Input is empty or whitespace-only.

MissingAtSign

Missing @ separator.

MultipleAtSigns

Multiple @ outside of quoted local-part.

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).

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 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.
