was already implemented:impl<T> FromIterator<Option<T::Native>> for ChunkedArray<T>
Traits
Functions
- Transform to physical type and coerce floating point and similar sized integer to a bit representation to reduce compiler bloat
- This takes ownership of the DataFrame so that drop is called earlier.
- This takes ownership of the DataFrame so that drop is called earlier. Does not check if schema is correct
- ensure that nulls are propagated to both arrays
- Concat the DataFrames to a single DataFrame.
- Concat the DataFrames to a single DataFrame.
- Given two datatypes, determine the supertype that both types can safely be cast to
- Given two datatypes, determine the supertype that both types can safely be cast to
- A utility that allocates an
UnstableSeries
. The applied function can then use that series container to save heap allocations and swap arrow arrays.
