Expand description
Apply kernels on the arrow array chunks in a ChunkedArray.
Required Methods§
sourcefn apply_kernel(&self, f: &dyn Fn(&A) -> Box<dyn Array>) -> Self
fn apply_kernel(&self, f: &dyn Fn(&A) -> Box<dyn Array>) -> Self
Apply kernel and return result as a new ChunkedArray.
sourcefn apply_kernel_cast<S>(
&self,
f: &dyn Fn(&A) -> Box<dyn Array>
) -> ChunkedArray<S>where
S: PolarsDataType,
fn apply_kernel_cast<S>(
&self,
f: &dyn Fn(&A) -> Box<dyn Array>
) -> ChunkedArray<S>where
S: PolarsDataType,
Apply a kernel that outputs an array of different type.
Object Safety§
This trait is not object safe.
