Describes why type checking of a user defined type 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.

NotUdt

The CQL type is not a user defined type.

ValuesMissingForUdtFields

The CQL UDT type does not have some fields that is required in the Rust struct.

Fields

field_names: Vec<&'static str>

Names of fields that the Rust struct requires but are missing in the CQL UDT.

FieldNameMismatch

A different field name was expected at given position.

Fields

position: usize

Index of the field in the Rust struct.

rust_field_name: String

The name of the Rust field.

db_field_name: String

The name of the CQL UDT field.

ExcessFieldInUdt

UDT contains an excess field, which does not correspond to any Rust struct’s field.

Fields

db_field_name: String

The name of the CQL UDT field.

DuplicatedField

Duplicated field in serialized data.

Fields

field_name: String

The name of the duplicated field.

TooFewFields

Fewer fields present in the UDT than required by the Rust type.

Fields

required_fields: Vec<&'static str>

present_fields: Vec<String>

FieldTypeCheckFailed

Type check failed between UDT and Rust type field.

Fields

field_name: String

The name of the field whose type check failed.

err: TypeCheckError

Inner type check error that occurred.
