Function mz_sql::plan::query::plan_root_query

pub fn plan_root_query(
    scx: &StatementContext<'_>,
    query: Query<Aug>,
    lifetime: QueryLifetime
) -> Result<PlannedRootQuery<HirRelationExpr>, PlanError>

Plans a top-level query, returning the HirRelationExpr describing the query plan, the RelationDesc describing the shape of the result set, a RowSetFinishing describing post-processing that must occur before results are sent to the client, and the types of the parameters in the query, if any were present.

Note that the returned RelationDesc describes the expression after applying the returned RowSetFinishing.
