Struct XmlDeserializer 

pub struct XmlDeserializer<'a> { /* private fields */ }

XML deserializer that implements the ShapeDeserializer trait.

Wraps the existing aws_smithy_xml::decode SAX-like API and provides schema-driven dispatch for struct members, lists, and maps.

The deserializer holds the input as &'a [u8] throughout. For aggregate reads (read_struct, read_list, read_map) we construct a fresh Document over input on demand. For scalar reads we either parse input to extract the root element’s text, or — when a parent aggregate has already extracted the leaf text from its child element — take the pre-extracted text directly via text.

Sibling dispatch within an aggregate read avoids per-iteration XmlDeserializer construction by reusing &mut self through dispatch_subslice / dispatch_text helpers, which save and restore the relevant state across the closure call.

Trait Implementations

impl ShapeDeserializer for XmlDeserializer<'_>

fn skip_value(&mut self) -> Result<(), SerdeError>

Nothing to advance. read_struct delimits each child before dispatching it — either as an owned sub-slice or as pre-extracted text — and the child’s ScopedDecoder is dropped, which moves the parent’s tokenizer past the closing tag regardless of what the consumer did. Advancing again here would consume a sibling element.

fn read_struct( &mut self, schema: &Schema<'_>, consumer: &mut dyn FnMut(&Schema<'_>, &mut dyn ShapeDeserializer) -> Result<(), SerdeError>, ) -> Result<(), SerdeError>

Reads a structure from the deserializer.

fn read_list( &mut self, _schema: &Schema<'_>, consumer: &mut dyn FnMut(&mut dyn ShapeDeserializer) -> Result<(), SerdeError>, ) -> Result<(), SerdeError>

Reads a list from the deserializer.

fn read_map( &mut self, schema: &Schema<'_>, consumer: &mut dyn FnMut(String, &mut dyn ShapeDeserializer) -> Result<(), SerdeError>, ) -> Result<(), SerdeError>

Reads a map from the deserializer.

fn read_boolean(&mut self, _schema: &Schema<'_>) -> Result<bool, SerdeError>

Reads a boolean value.

fn read_byte(&mut self, _schema: &Schema<'_>) -> Result<i8, SerdeError>

Reads a byte (i8) value.

fn read_short(&mut self, _schema: &Schema<'_>) -> Result<i16, SerdeError>

Reads a short (i16) value.

fn read_integer(&mut self, _schema: &Schema<'_>) -> Result<i32, SerdeError>

Reads an integer (i32) value.

fn read_long(&mut self, _schema: &Schema<'_>) -> Result<i64, SerdeError>

Reads a long (i64) value.

fn read_float(&mut self, _schema: &Schema<'_>) -> Result<f32, SerdeError>

Reads a float (f32) value.

fn read_double(&mut self, _schema: &Schema<'_>) -> Result<f64, SerdeError>

Reads a double (f64) value.

fn read_big_integer( &mut self, _schema: &Schema<'_>, ) -> Result<BigInteger, SerdeError>

Reads a big integer value.

fn read_big_decimal( &mut self, _schema: &Schema<'_>, ) -> Result<BigDecimal, SerdeError>

Reads a big decimal value.

fn read_string(&mut self, _schema: &Schema<'_>) -> Result<String, SerdeError>

Reads a string value.

fn read_blob(&mut self, _schema: &Schema<'_>) -> Result<Blob, SerdeError>

Reads a blob (byte array) value.

fn read_timestamp( &mut self, schema: &Schema<'_>, ) -> Result<DateTime, SerdeError>

Reads a timestamp value.

fn read_document( &mut self, _schema: &Schema<'_>, ) -> Result<SmithyDocument, SerdeError>

Reads a document value.

fn read_string_list( &mut self, _schema: &Schema<'_>, ) -> Result<Vec<String>, SerdeError>

Reads a list of strings.

fn read_blob_list( &mut self, _schema: &Schema<'_>, ) -> Result<Vec<Blob>, SerdeError>

Reads a list of blobs.

fn read_integer_list( &mut self, _schema: &Schema<'_>, ) -> Result<Vec<i32>, SerdeError>

Reads a list of integers.

fn read_long_list( &mut self, _schema: &Schema<'_>, ) -> Result<Vec<i64>, SerdeError>

Reads a list of longs.

fn read_string_string_map( &mut self, schema: &Schema<'_>, ) -> Result<HashMap<String, String>, SerdeError>

Reads a map with string values.

fn is_null(&self) -> bool

Checks if the current value is null.

fn container_size(&self) -> Option<usize>

Returns the size of the current container if known.

fn read_null(&mut self) -> Result<(), SerdeError>

Consumes a null value, advancing past it.
