Runtime api for testing the execution of a runtime upgrade.

Provided Methods

fn on_runtime_upgrade(
    &self,
    __runtime_api_at_param__: &BlockId<Block>
) -> 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.

fn on_runtime_upgrade_with_context(
    &self,
    __runtime_api_at_param__: &BlockId<Block>,
    context: ExecutionContext
) -> 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.

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

Execute the given block, but don’t check that its state root matches that of yours.

This is only sensible where the incoming block is from a different network, yet it has the same block format as the runtime implementing this API.

fn execute_block_with_context(
    &self,
    __runtime_api_at_param__: &BlockId<Block>,
    context: ExecutionContext,
    block: Block,
    state_root_check: bool,
    try_state: TryStateSelect
) -> Result<Weight, ApiError>

Execute the given block, but don’t check that its state root matches that of yours.

This is only sensible where the incoming block is from a different network, yet it has the same block format as the runtime implementing this API.
