}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.
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety".
