Trait xso::FromXml

pub trait FromXml {
    type Builder: FromEventsBuilder<Output = Self>;

    // Required method
    fn from_events(
        name: QName,
        attrs: AttrMap,
    ) -> Result<Self::Builder, FromEventsError>;
}

Trait allowing to construct a struct from a stream of rxml::Event items.

To use this, first call FromXml::from_events with the qualified name and the attributes of the corresponding rxml::Event::StartElement event. If the call succeeds, the returned builder object must be fed with the events representing the contents of the element, and then with the EndElement event.

The StartElement passed to from_events must not be passed to feed.

Required Associated Types

type Builder: FromEventsBuilder<Output = Self>

A builder type used to construct the element.

Required Methods

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

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

If the passed qualified name and attrs match the element’s type, the Self::Builder is returned and should be fed with XML events by the caller.

Otherwise, an appropriate error is returned.

Object Safety

This trait is not object safe.
