Describes why deserialization of some of the built-in types failed.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

BadDate

Failed to deserialize one of date’s fields.

Fields

date_field: &'static str

err: LowLevelDeserializationError

BadDecimalScale(LowLevelDeserializationError)

Failed to deserialize decimal’s scale.

RawCqlBytesReadError(LowLevelDeserializationError)

Failed to deserialize raw bytes of cql value.

CustomTypeNotSupported(String)

Returned on attempt to deserialize a value of custom type.

ExpectedNonNull

Expected non-null value, got null.

ByteLengthMismatch

The length of read value in bytes is different than expected for the Rust type.

Fields

expected: usize

got: usize

ExpectedAscii

Expected valid ASCII string.

InvalidUtf8(Utf8Error)

Invalid UTF-8 string.

ValueOverflow

The read value is out of range supported by the Rust type.

BadInetLength

The length of read value in bytes is not suitable for IP address.

Fields

got: usize

SetOrListError(SetOrListDeserializationErrorKind)

A deserialization failure specific to a CQL set or list.

MapError(MapDeserializationErrorKind)

A deserialization failure specific to a CQL map.

TupleError(TupleDeserializationErrorKind)

A deserialization failure specific to a CQL tuple.

UdtError(UdtDeserializationErrorKind)

A deserialization failure specific to a CQL UDT.
