Expand description
Cast ChunkedArray<T>
to ChunkedArray<N>
Required Methods
sourcefn cast(&self, data_type: &DataType) -> PolarsResult<Series>
fn cast(&self, data_type: &DataType) -> PolarsResult<Series>
Cast a [ChunkedArray]
to [DataType]
sourcefn cast_unchecked(&self, data_type: &DataType) -> PolarsResult<Series>
fn cast_unchecked(&self, data_type: &DataType) -> PolarsResult<Series>
Does not check if the cast is a valid one and may over/underflow
Implementors
impl ChunkCast for BooleanChunked
impl ChunkCast for ListChunked
We cannot cast anything to or from List/LargeList So this implementation casts the inner type
