Enum sp_api::InitializeBlock

pub enum InitializeBlock<'a, Block: BlockT> {
    Skip,
    Do(&'a RefCell<Option<BlockId<Block>>>),
}

Before calling any runtime api function, the runtime need to be initialized at the requested block. However, some functions like execute_block or initialize_block itself don’t require to have the runtime initialized at the requested block.

call_api_at is instructed by this enum to do the initialization or to skip it.

Variants

Skip

Skip initializing the runtime for a given block.

This is used by functions who do the initialization by themselves or don’t require it.

Do(&'a RefCell<Option<BlockId<Block>>>)

Initialize the runtime for a given block.

If the stored BlockId is Some(_), the runtime is currently initialized at this block.
