[−][src]Function casper_client::get_item

pub fn get_item(
    maybe_rpc_id: &str, 
    node_address: &str, 
    verbose: bool, 
    state_root_hash: &str, 
    key: &str, 
    path: &str
) -> Result<JsonRpc, Error>

Retrieves a stored value from the network.

  • maybe_rpc_id is the JSON-RPC identifier, applied to the request and returned in the response. If it can be parsed as an i64 it will be used as a JSON integer. If empty, a random i64 will be assigned. Otherwise the provided string will be used verbatim.
  • node_address is the hostname or IP and port of the node on which the HTTP service is running, e.g. "http://127.0.0.1:7777".
  • When verbose is true, the JSON-RPC request will be printed to stdout.
  • state_root_hash must be a hex-encoded, 32-byte hash digest.
  • key must be a formatted PublicKey or Key. This will take one of the following forms:
