Struct PlanNormalizer

Source

pub struct PlanNormalizer { /* private fields */ }

Expand description

Plan normalizer - the stability core

Implementations§

Source §

impl PlanNormalizer

Source

pub fn new() -> PlanNormalizer

Create a new normalizer

Source

pub fn add_validator(&mut self, validator: Box<dyn PlanValidator>)

Add a validator

Source

pub fn add_fixer(&mut self, fixer: Box<dyn PlanFixer>)

Add a fixer

Source

pub fn register_action(&mut self, name: impl Into<String>)

Register a known action

Source

pub fn deterministic_contract(&self) -> Option<Value>

Returns the immutable contract required to replay normalization after a process restart.

Custom trait-object validators and fixers have no stable identity in v1, so a normalizer containing either is intentionally not replayable.

Source

pub fn normalize(&self, plan: Plan) -> Result<NormalizedPlan, NormalizeError>

Normalize a plan

Trait Implementations§

impl Default for PlanNormalizer

Source §

fn default() -> PlanNormalizer

impl UnsafeUnpin for PlanNormalizer

Blanket Implementations§

Source §

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

Source §

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

Source §

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

Source §

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

Source §

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

Source §

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

Mutably borrows from an owned value. Read more

Source §

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

Source §

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.

Source §

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.

Source §

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.

Source §

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.

Source §

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

Source §

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.
