Function assert_series_equal 

pub fn assert_series_equal(
    left: &Series,
    right: &Series,
    options: SeriesEqualOptions,
) -> PolarsResult<()>

Verifies that two Series are equal according to a set of configurable criteria.

This function serves as the main entry point for comparing Series, checking various metadata properties before comparing the actual values.

Arguments

• left - The first Series to compare
• right - The second Series to compare
• options - A SeriesEqualOptions struct containing configuration parameters:
  • check_names - If true, verifies Series names match
  • check_dtypes - If true, verifies data types match
  • check_order - If true, elements must be in the same order
  • check_exact - If true, requires exact equality for float values
  • rel_tol - Relative tolerance for float comparison
  • abs_tol - Absolute tolerance for float comparison
  • categorical_as_str - If true, converts categorical Series to strings before comparison

Returns

• Ok(()) if Series match according to all specified criteria
• Err with details about the first mismatch encountered:
  • Length mismatch
  • Name mismatch (if checking names)
  • Data type mismatch (if checking dtypes)
  • Value mismatches (via assert_series_values_equal)

Order of Checks

1. Series length
2. Series names (if check_names is true)
3. Data types (if check_dtypes is true)
4. Series values (delegated to assert_series_values_equal)
