• UInt64Type
• VectorType
  VectorType is a data type for vector data with a fixed dimension. The type of items in the vector is float32. It is stored as binary data that contains the concatenated float32 values.

Enums

• DurationType
• IntervalType
  The “calendar” interval is a type of time interval that does not have a precise duration without taking into account a specific base timestamp.
• TimeType
• TimestampType

Constants

• JSON_TYPE_NAME

Traits

• LogicalPrimitiveType
  Trait bridging the logical primitive type with [ArrowPrimitiveType].
• WrapperType
  Represents the wrapper type that wraps a native type using the newtype pattern, such as Date is a wrapper type for the underlying native type i32.

Functions

• json_type_value_to_string
  Converts a json type value to string
• parse_string_to_json_type_value
  Parses a string to a json type value
• parse_string_to_vector_type_value
  Parses a string to a vector type value Valid input format: “[1.0,2.0,3.0]”, “[1.0, 2.0, 3.0]”
• vector_type_value_to_string
  Converts a vector type value to string for example: [1.0, 2.0, 3.0] -> “[1.0,2.0,3.0]”
