Expand description
Parameters for CallApiAt::call_api_at
.
Fields
core_api: &'a C
A reference to something that implements the Core
api.
at: &'a BlockId<Block>
The block id that determines the state that should be setup when calling the function.
function: &'static str
The name of the function that should be called.
native_call: Option<NC>
An optional native call that calls the function
. This is an optimization to call into a
native runtime without requiring to encode/decode the parameters. The native runtime can
still be called when this value is None
, we then just fallback to encoding/decoding the
parameters.
arguments: Vec<u8>
The encoded arguments of the function.
overlayed_changes: &'a RefCell<OverlayedChanges>
The overlayed changes that are on top of the state.
storage_transaction_cache: &'a RefCell<StorageTransactionCache<Block, Backend>>
The cache for storage transactions.
initialize_block: InitializeBlock<'a, Block>
Determines if the function requires that initialize_block
should be called before calling
the actual function.
context: ExecutionContext
The context this function is executed in.
recorder: &'a Option<ProofRecorder<Block>>
The optional proof recorder for recording storage accesses.
