Struct Ownership Checker &nbsp; Copy item path

impl<'a> OwnershipChecker<'a>

pub fn new(interner: &'a Interner) -> Self

pub fn check_program_collect( &mut self, stmts: &[Stmt<'_>], ) -> Vec<OwnershipFinding>

Collect EVERY ownership finding instead of bailing at the first.

After each finding the offending variable resets to Owned, so one use-after-move does not cascade into errors on every later use. OwnershipChecker::check_program keeps the strict fail-fast contract for compile paths.

pub fn var_states(&self) -> &HashMap<Symbol, VarState>

Access the current variable ownership states.

pub fn check_program( &mut self, stmts: &[Stmt<'_>], ) -> Result<(), OwnershipError>

Check a program for ownership violations

Auto Trait Implementations§

impl<'a> UnwindSafe for OwnershipChecker<'a>

Blanket Implementations§

impl<T> Any for T
where T: 'static + ?Sized,

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

impl<T> Borrow<T> for T
where T: ?Sized,

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

impl<T> BorrowMut<T> for T
where T: ?Sized,

fn borrow_mut(&mut self) -> &mut T

Mutably borrows from an owned value. Read more

impl<T> Downcast for T
where T: Any,

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.

impl<T> DowncastSync for T
where T: Any + Send + Sync,

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Sync + Send>

Convert Arc<Trait> (where Trait: Downcast) to Arc<Any>. Arc<Any> can then be further downcast into Arc<ConcreteType> where ConcreteType implements Trait.
