Function create_random_array

Source 
pub fn create_random_array(
    field: &Field,
    size: usize,
    null_density: f32,
    true_density: f32,
) -> Result<ArrayRef>
Expand description

Create a random ArrayRef from a DataType with a length, null density and true density (for BooleanArray).

ยงArguments

  • field - The field containing the data type for which to create a random array
  • size - The number of elements in the generated array
  • null_density - The approximate fraction of null values in the resulting array (0.0 to 1.0)
  • true_density - The approximate fraction of true values in boolean arrays (0.0 to 1.0)
