Detailed Description

Strong type wrapper for the desired standard error constructor parameter.

Use this type to construct an approx_distinct_count with a desired error tolerance instead of specifying precision directly.

Example:

auto sketch = cudf::approx_distinct_count(
  table, cudf::approx_distinct_count::desired_standard_error{0.01});
