Struct Data 

pub struct Data<T> {
    pub data: T,
    pub block_height: u64,
    pub block_hash: CryptoHash,
}

A wrapper around a generic query result that includes the block height and block hash at which the query was executed

Fields

data: T

The data returned by the query

block_height: u64

The block height at which the query was executed

block_hash: CryptoHash

The block hash at which the query was executed
