Enum tp_api::InitializeBlock [−][src]
Expand description
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 initializing the runtime for a given block.
This is used by functions who do the initialization by themselves or don’t require it.
Initialize the runtime for a given block.
If the stored BlockId
is Some(_)
, the runtime is currently initialized at this block.
