Function node_count 

pub fn node_count(
    document: &str,
    variables: &Variables,
) -> Result<u64, NodeCountError>

The most nodes document could be asked to return under variables.

worst_case_node_count is this under largest_page_sizes, and the accounting in accounting is this under the bindings one request really sent — one spelling of the calculation, so a bound checked offline and a cost recorded at run time cannot come to disagree. The rules themselves live in github_graphql_node_count::node_count.

Errors

Returns the calculation’s own NodeCountError when document does not parse, holds no single operation, or binds a page size variables does not name.
