impl Rule for CountOfNullableColumn

fn meta(&self) -> &'static RuleMeta

fn check_expr(&self, expr: &Expr, ctx: &LintCtx<'_>, out: &mut Vec<Diagnostic>)

fn check_statement( &self, _stmt: &SqltStatement, _ctx: &LintCtx<'_>, _out: &mut Vec<Diagnostic>, )

fn check_query( &self, _query: &Query, _depth: usize, _ctx: &LintCtx<'_>, _out: &mut Vec<Diagnostic>, )

depth is 0 for the outermost Query of a statement and increases for nested queries (subqueries, derived tables, CTEs, scalar subqueries). Rules that should only flag nested constructs can guard on depth > 0.
