Expand description

Parameters for CallApiAt::call_api_at.

Fields

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.

context: ExecutionContext

The context this function is executed in.

recorder: &'a Option<ProofRecorder<Block>>

The optional proof recorder for recording storage accesses.
