Runtime api for testing the execution of a runtime upgrade.

Provided Methods

fn on_runtime_upgrade( &self, __runtime_api_at_param__: <Block as BlockT>::Hash, checks: UpgradeCheckSelect ) -> Result<(Weight, Weight), ApiError>

dry-run runtime upgrades, returning the total weight consumed.

This should do EXACTLY the same operations as the runtime would have done in the case of a runtime upgrade (e.g. pallet ordering must be the same)

Returns the consumed weight of the migration in case of a successful one, combined with the total allowed block weight of the runtime.

If checks is true, pre_migrate and post_migrate of each migration and try_state of all pallets will be executed. Else, no. If checks are executed, the PoV tracking is likely inaccurate.

fn execute_block( &self, __runtime_api_at_param__: <Block as BlockT>::Hash, block: Block, state_root_check: bool, signature_check: bool, try_state: TryStateSelect ) -> Result<Weight, ApiError>

Execute the given block, but optionally disable state-root and signature checks.

Optionally, a number of try_state hooks can also be executed after the block execution.
