Module cast

Cast kernels to convert [ArrayRef] between supported datatypes.

See cast_with_options for more information on specific conversions.

Example:

// int32 to float64
let a = Int32Array::from(vec![5, 6, 7]);
let b = cast(&a, &DataType::Float64).unwrap();
let c = b.as_primitive::<Float64Type>();
assert_eq!(5.0, c.value(0));
assert_eq!(6.0, c.value(1));
assert_eq!(7.0, c.value(2));

Functions

• adjust_timestamp_to_timezone 🔒
• as_time_res_with_timezone 🔒
• bool_to_numeric_cast 🔒
• can_cast_types
  Return true if a value of type from_type can be cast into a value of to_type.
• cast
  Cast array to the provided data type and return a new Array with type to_type, if possible.
• cast_binary_to_fixed_size_binary 🔒
  Helper function to cast from one BinaryArray or ‘LargeBinaryArray’ to ‘FixedSizeBinaryArray’.
• cast_bool_to_numeric 🔒
  Cast Boolean types to numeric
• cast_byte_container 🔒
  Helper function to cast from one ByteArrayType to another and vice versa. If the target one (e.g., LargeUtf8) is too large for the source array it will return an Error.
• cast_duration_to_interval 🔒
  Cast the array from duration and interval
• cast_fixed_size_binary_to_binary 🔒
  Helper function to cast from ‘FixedSizeBinaryArray’ to one BinaryArray or ‘LargeBinaryArray’. If the target one is too large for the source array it will return an Error.
• cast_integer_to_decimal 🔒
• cast_interval_day_time_to_interval_month_day_nano 🔒
  Cast the array from interval day time to month day nano
• cast_interval_year_month_to_interval_month_day_nano 🔒
  Cast the array from interval year month to month day nano
• cast_month_day_nano_to_duration 🔒
  Cast the array from interval to duration
• cast_numeric_arrays 🔒
  Convert Array into a PrimitiveArray of type, and apply numeric cast
• cast_numeric_to_binary 🔒
• cast_numeric_to_bool 🔒
  Cast numeric types to Boolean
• cast_reinterpret_arrays 🔒
  Cast the primitive array using [PrimitiveArray::reinterpret_cast]
• cast_view_to_byte 🔒
  Helper function to cast from one ByteViewType array to ByteArrayType array.
• cast_with_options
  Try to cast array to to_type if possible.
