pub fn build<'a>(
plan: &'a Plan,
catalog: &'a Catalog,
) -> Result<Box<dyn Operator + 'a>>Expand description
Builds the operator tree for a plan’s root, for a query nothing will stop.
Every seam is left at its default, which is what a caller with no session behind it wants and is what the tests in this crate are written against.
§Errors
If the plan names a table or a column the catalog does not have, if an expression is malformed
in a way Plan::validate would have caught, or anything an operator’s construction reports.
