compute_cast only.Expand description
Defines different casting operators such as cast or primitive_to_binary.
Structs
options defining how Cast kernels behave
Functions
Conversion of binary
Cast BinaryArray to DictionaryArray, also known as packing.
Conversion of binary
Conversion to utf8
Casts a BinaryArray to a PrimitiveArray, making any uncastable value a Null.
Conversion to utf8
Casts the BooleanArray to a BinaryArray, casting trues to "1" and falses to "0"
Casts the BooleanArray to a PrimitiveArray.
Casts the BooleanArray to a Utf8Array, casting trues to "1" and falses to "0"
Return true if a value of type from_type can be cast into a
value of to_type. Note that such as cast may be lossy.
Conversion of dates
Conversion of dates
Casts days_mss to months_days_ns. This operation is infalible and lossless.
Returns a PrimitiveArray<i128> with the casted values. Values are None on overflow
Returns a PrimitiveArray<i128> with the casted values. Values are None on overflow
Returns a PrimitiveArray<i128> with the casted values. Values are None on overflow
Casts a DictionaryArray to a new DictionaryArray backed by a
different physical type of the keys, while keeping the values equal.
Casts a DictionaryArray to a new DictionaryArray by keeping the
keys and casting the values to values_type.
Casts a DictionaryArray to its values’ DataType, also known as unpacking.
The resulting array has the same length.
Casts f16 into f32
Returns a PrimitiveArray<i128> with the casted values. Values are None on overflow
Returns a PrimitiveArray<i128> with the casted values. Values are None on overflow
Casts months represented as i32s to months_days_ns. This operation is infalible and lossless.
Returns a Utf8Array where every element is the utf8 representation of the timestamp in the rfc3339 format.
Casts a BinaryArray to a PrimitiveArray at best-effort using lexical_core::parse_partial, making any uncastable value as zero.
Casts a Utf8Array to a PrimitiveArray at best-effort using lexical_core::parse_partial, making any uncastable value as zero.
Cast PrimitiveArray as a PrimitiveArray
Same as number as to_number_type in rust
Returns a BinaryArray where every element is the binary representation of the number.
Returns a BooleanArray where every element is different from zero.
Validity is preserved.
Cast PrimitiveArray to DictionaryArray. Also known as packing.
Cast PrimitiveArray to a PrimitiveArray of another physical type via numeric conversion.
Cast PrimitiveArray to a PrimitiveArray of the same physical type.
This is O(1).
Returns a Utf8Array where every element is the utf8 representation of the number.
Conversion of time

Conversion of timestamp
Returns a Utf8Array where every element is the utf8 representation of the timestamp in the rfc3339 format.
Conversion of utf8
Conversion to binary
Casts a Utf8Array to a Date32 primitive, making any uncastable value a Null.
Casts a Utf8Array to a Date64 primitive, making any uncastable value a Null.
Cast Utf8Array to DictionaryArray, also known as packing.
Conversion of utf8
crate::temporal_conversions::utf8_to_timestamp_ns applied for RFC3339 formatting
Casts a Utf8Array to a PrimitiveArray, making any uncastable value a Null.
