mask

Function mask 

Source
pub fn mask(array: &dyn Array, mask: &Mask) -> VortexResult<ArrayRef>
👎Deprecated: use array.mask(mask_array) via ArrayBuiltins instead
Expand description

Replace values with null where the mask is true.

The returned array is nullable but otherwise has the same dtype and length as array.

This function returns a lazy ScalarFnArray wrapping the Mask expression that defers the actual masking operation until execution time. The mask is inverted (true=mask-out becomes true=keep) and passed as a boolean child to the expression.
