Struct Deserializer

pub struct Deserializer<R: Read, B: BufferedXmlReader<R> = RootXmlBuffer<R>> { /* private fields */ }

Implementations

impl<'de, R: Read> Deserializer<R, RootXmlBuffer<R>>

pub fn new(reader: EventReader<R>) -> Self

pub fn new_from_reader(reader: R) -> Self

pub fn non_contiguous_seq_elements(self, set: bool) -> Self

Configures whether the deserializer should search all sibling elements when building a sequence. Not required if all XML elements for sequences are adjacent. Disabled by default. Enabling this option may incur additional memory usage.
