Struct sql::plan::transform_ast::Desugarer

struct Desugarer {
    status: Result<(), PlanError>,
    recursion_guard: RecursionGuard,
}

Removes syntax sugar to simplify the planner.

For example, <expr> NOT IN (<subquery>) is rewritten to expr <> ALL (<subquery>).

Fields

status: Result<(), PlanError>

recursion_guard: RecursionGuard

Implementations

impl Desugarer

fn visit_internal<F, X>(&mut self, f: F, x: X) where
    F: Fn(&mut Self, X) -> Result<(), PlanError>, 

fn new() -> Desugarer

fn visit_expr_mut_internal(
    &mut self,
    expr: &mut Expr<Raw>
) -> Result<(), PlanError>

Trait Implementations

impl CheckedRecursion for Desugarer

fn recursion_guard(&self) -> &RecursionGuard

Extracts a reference to the recursion guard embedded within the type.

fn checked_recur<F, T, E>(&self, f: F) -> Result<T, E> where
    F: FnOnce(&Self) -> Result<T, E>,
    E: From<RecursionLimitError>, 

Checks whether it is safe to recur and calls f if so.

fn checked_recur_mut<F, T, E>(&mut self, f: F) -> Result<T, E> where
    F: FnOnce(&mut Self) -> Result<T, E>,
    E: From<RecursionLimitError>, 

Like CheckedRecursion::checked_recur, but operates on a mutable reference to Self.
