Trait Implementations

impl AsXml for Optional

type ItemIter<'xso_proc_as_xml_iter_lifetime> = OptionalAsXmlIterator<'xso_proc_as_xml_iter_lifetime>

The iterator type.

fn as_xml_iter(&self) -> Result<Self::ItemIter<'_>, Error>

Return an iterator which emits the contents of the struct or enum as serialisable Item items.

impl Clone for Optional

fn clone(&self) -> Optional

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Optional

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

Formats the value using the given formatter.

impl From<Optional> for Element

fn from(other: Optional) -> Self

Converts to this type from the input type.

impl FromXml for Optional

type Builder = OptionalFromXmlBuilder

A builder type used to construct the element.

fn from_events( name: QName, attrs: AttrMap, ) -> Result<Self::Builder, FromEventsError>

Attempt to initiate the streamed construction of this struct from XML.

impl PartialEq for Optional

fn eq(&self, other: &Optional) -> 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 TryFrom<Element> for Optional

type Error = FromElementError

The type returned in the event of a conversion error.

fn try_from(other: Element) -> Result<Self, Self::Error>

Performs the conversion.
