Function datafusion_physical_expr::utils::get_indices_of_matching_exprs

pub fn get_indices_of_matching_exprs<T: Borrow<Arc<dyn PhysicalExpr>>, F: FnOnce() -> EquivalenceProperties>(
    targets: impl IntoIterator<Item = T>,
    items: &[Arc<dyn PhysicalExpr>],
    equal_properties: F
) -> Vec<usize>

This function finds the indices of targets within items, taking into account equivalences according to equal_properties.
