Struct TrackingBackingStore 

pub struct TrackingBackingStore<'a> { /* private fields */ }

A BackingStore that records every object read through it.

Captures the objects execution loads beyond the declared inputs (dynamic fields, received objects, system packages), whose superseded versions must be relocated by value. Wrap the store for a single execution, then take the recorded objects with into_read_objects.

Trait Implementations

impl BackingPackageStore for TrackingBackingStore<'_>

fn get_package_object( &self, package_id: &ObjectId, ) -> IotaResult<Option<PackageObject>>

impl ChildObjectResolver for TrackingBackingStore<'_>

fn read_child_object( &self, parent: &ObjectId, child: &ObjectId, child_version_upper_bound: Version, ) -> IotaResult<Option<Object>>

child must have an Object ownership equal to parent.

fn get_object_received_at_version( &self, owner: &ObjectId, receiving_object_id: &ObjectId, receive_object_at_version: Version, epoch_id: EpochId, ) -> IotaResult<Option<Object>>

receiving_object_id must have an Address ownership equal to owner. get_object_received_at_version must be the exact version at which the object will be received, and it cannot have been previously received at that version. NB: An object not existing at that version, and not having valid access to the object will be treated exactly the same and Ok(None) must be returned.

impl ObjectStore for TrackingBackingStore<'_>

fn try_get_object(&self, object_id: &ObjectId) -> Result<Option<Object>>

fn try_get_object_by_key( &self, object_id: &ObjectId, version: VersionNumber, ) -> Result<Option<Object>>

fn get_object(&self, object_id: &ObjectId) -> Option<Object>

Non-fallible version of try_get_object.

fn get_object_by_key( &self, object_id: &ObjectId, version: VersionNumber, ) -> Option<Object>

Non-fallible version of try_get_object_by_key.

fn try_multi_get_objects( &self, object_ids: &[ObjectId], ) -> Result<Vec<Option<Object>>>

fn multi_get_objects(&self, object_ids: &[ObjectId]) -> Vec<Option<Object>>

Non-fallible version of try_multi_get_objects.

fn try_multi_get_objects_by_key( &self, object_keys: &[ObjectKey], ) -> Result<Vec<Option<Object>>>

fn multi_get_objects_by_key( &self, object_keys: &[ObjectKey], ) -> Vec<Option<Object>>

Non-fallible version of try_multi_get_objects_by_key.
