Struct StorageAccessParams

pub struct StorageAccessParams<B: Block> {
    pub state_root: B::Hash,
    pub storage_proof: StorageProof,
    pub payload: StorageAccessPayload,
    pub is_dry_run: bool,
}

Parameters for benchmarking storage access on block validation.

On dry-run, the storage access is not performed to measure the cost of the runtime call.

Fields

state_root: B::Hash

storage_proof: StorageProof

payload: StorageAccessPayload

is_dry_run: bool

On dry-run, we don’t read/write to the storage.

Implementations

impl<B: Block> StorageAccessParams<B>

pub fn new_read( state_root: B::Hash, storage_proof: StorageProof, payload: Vec<(Vec<u8>, Option<ChildInfo>)>, ) -> Self

Create a new params for reading from the storage.

pub fn new_write( state_root: B::Hash, storage_proof: StorageProof, payload: (Vec<(Vec<u8>, Vec<u8>)>, Option<ChildInfo>), ) -> Self

Create a new params for writing to the storage.

pub fn as_dry_run(&self) -> Self

Create a dry-run version of the params.
