(De)serialization error

Variants

Custom(String)

Serde custom error

InvalidXml(Error)

Xml parsing error

InvalidInt(ParseIntError)

Cannot parse to integer

InvalidFloat(ParseFloatError)

Cannot parse to float

InvalidBoolean(String)

Cannot parse specified value to boolean

KeyNotRead

This error indicates an error in the Deserialize implementation when read a map or a struct: MapAccess::next_value[_seed] was called before MapAccess::next_key[_seed].

You should check your types, that implements corresponding trait.

UnexpectedStart(Vec<u8>)

Deserializer encounter a start tag with a specified name when it is not expecting. This happens when you try to deserialize a primitive value (numbers, strings, booleans) from an XML element.

UnexpectedEnd(Vec<u8>)

Deserializer encounter an end tag with a specified name when it is not expecting. Usually that should not be possible, because XML reader is not able to produce such stream of events that lead to this error.

If you get this error this likely indicates and error in the quick_xml. Please open an issue at https://github.com/tafia/quick-xml, provide your Rust code and XML input.

UnexpectedEof

The Reader produced Event::Eof when it is not expecting, for example, after producing Event::Start but before corresponding Event::End.

ExpectedStart

This error indicates that deserialize_struct was called, but there is no any XML element in the input. That means that you try to deserialize a struct not from an XML element.

Unsupported(Cow<'static, str>)

An attempt to deserialize to a type, that is not supported by the XML store at current position, for example, attempt to deserialize struct from attribute or attempt to deserialize binary data.

Serialized type cannot be represented in an XML due to violation of the XML rules in the final XML document. For example, attempt to serialize a HashMap<{integer}, ...> would cause this error because XML name cannot start from a digit or a hyphen (minus sign). The same result would occur if map key is a complex type that cannot be serialized as a primitive type (i.e. string, char, bool, unit struct or unit variant).

TooManyEvents(NonZeroUsize)

Available on crate feature overlapped-lists only.

Too many events were skipped while deserializing a sequence, event limit exceeded. The limit was provided as an argument

Trait Implementations

impl Clone for DeError

fn clone(&self) -> DeError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DeError

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

Formats the value using the given formatter.

impl Display for DeError

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

Formats the value using the given formatter.

impl Error for DeError

fn custom<T: Display>(msg: T) -> Self

Raised when there is general error when deserializing a type.

fn invalid_type(unexp: Unexpected<'_>, exp: &dyn Expected) -> Self

Raised when a Deserialize receives a type different from what it was expecting.

fn invalid_value(unexp: Unexpected<'_>, exp: &dyn Expected) -> Self

Raised when a Deserialize receives a value of the right type but that is wrong for some other reason.

fn invalid_length(len: usize, exp: &dyn Expected) -> Self

Raised when deserializing a sequence or map and the input data contains too many or too few elements.

fn unknown_variant(variant: &str, expected: &'static [&'static str]) -> Self

Raised when a Deserialize enum type received a variant with an unrecognized name.

fn unknown_field(field: &str, expected: &'static [&'static str]) -> Self

Raised when a Deserialize struct type received a field with an unrecognized name.

fn missing_field(field: &'static str) -> Self

Raised when a Deserialize struct type expected to receive a required field with a particular name but that field was not present in the input.

fn duplicate_field(field: &'static str) -> Self

Raised when a Deserialize struct type received more than one of the same field.

impl Error for DeError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting
