Enum hdbconnect_async::DeserializationError

pub enum DeserializationError {
    ConversionError(ConversionError),
    SerdeError(String),
    Usage(String),
    NotImplemented(&'static str),
    UnknownField(String),
    TrailingRows,

}

The errors that can arise while deserializing with serde_db::de.

Variants

ConversionError(ConversionError)

Deserialization failed due to a conversion error.

SerdeError(String)

Error reported from serde framework.

Usage(String)

The structure of the target object does not fit to the structure of the object being deserialized.

NotImplemented(&'static str)

Thrown by functions in the Deserializer interface that are not implemented. This exception should never be seen in practice.

UnknownField(String)

The target structure misses a field for which data are provided.

TrailingRows

The deserialization cannot consume all existing rows.

TrailingCols

The deserialization cannot consume all existing columns.

Trait Implementations

impl Debug for DeserializationError

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

Formats the value using the given formatter.

impl Display for DeserializationError

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

Formats the value using the given formatter.

impl Error for DeserializationError

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

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.

impl Error for DeserializationError

fn custom<T>(msg: T) -> DeserializationError

where T: Display,

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 From<ConversionError> for DeserializationError

fn from(source: ConversionError) -> DeserializationError

Converts to this type from the input type.

impl From<DeserializationError> for HdbError

fn from(source: DeserializationError) -> HdbError

Converts to this type from the input type.

impl From<HdbError> for DeserializationError

fn from(e: HdbError) -> DeserializationError

Converts to this type from the input type.
