Struct async_xml::reader::TryFromVisitor

pub struct TryFromVisitor<B, Target, FromType, E>where
    B: AsyncBufRead + Unpin,
    Target: TryFrom<FromType, Error = E>,
    FromType: FromXml<B>,{ /* private fields */ }

Generic visitor for forwarding all calls to an inner visitor and converting into the target type using its TryFrom implementation.

type Output = Target

Output type this Visitor returns

fn start_name() -> Option<&'static str>

Should return the expected starting tag name, if any

fn visit_tag(&mut self, name: &str) -> Result<(), Error>

Visit the starting tag with the given name

fn visit_text(&mut self, text: &str) -> Result<(), Error>

Visit any plain text contained in the element

fn visit_attribute(&mut self, name: &str, value: &str) -> Result<(), Error>

Visit an attribute with the given name and value

    &'life0 mut self,
    name: &'life1 str,
    reader: &'life2 mut PeekingReader<B>
