Trait for Factory that create objects based on versioning store

Required Associated Types

type Output

Factory will create only one object of a given type, so a FactoryAddress (impl VersioningFactory), will have type Output = Address

type Error

Error if object cannot be created (+ used for VersioningFactoryArgs)

type Arguments

Arguments struct in order to create Self::Output

Required Methods

fn get_component() -> MipComponent

Return the MipComponent associated with return type (Output) e.g. if type Output = Address, should return MipComponent::Address

fn get_versioning_store(&self) -> MipStore

Access to the MipStore

fn create( &self, args: &Self::Arguments, strategy: FactoryStrategy ) -> Result<Self::Output, Self::Error>

Create an object of type Self::Output

Provided Methods

fn get_latest_component_version_at( &self, ts: MassaTime ) -> Result<u32, FactoryError>

Get latest version at given timestamp (e.g. slot)

fn get_all_active_component_versions(&self) -> Vec<u32>

Get all versions in ‘Active state’ for the associated MipComponent

fn get_all_component_versions(&self) -> BTreeMap<u32, ComponentStateTypeId>

Get all versions (at any state) for the associated MipComponent

fn get_component_version_with_strategy( &self, strategy: FactoryStrategy ) -> Result<u32, FactoryError>

Get the version the current component with the given strategy

Implementors
