Struct ViewFunctionResult 

pub struct ViewFunctionResult {
    pub result: Vec<u8>,
    pub logs: Vec<String>,
    pub block_height: u64,
    pub block_hash: CryptoHash,
}

View function result from call_function RPC.

Fields

result: Vec<u8>

Result bytes (often JSON).

logs: Vec<String>

Logs emitted during view call.

block_height: u64

Block height of the query.

block_hash: CryptoHash

Block hash of the query.

Implementations

impl ViewFunctionResult

pub fn bytes(&self) -> &[u8]

Get the result as raw bytes.

pub fn as_string(&self) -> Result<String, FromUtf8Error>

Get the result as a string.

pub fn json<T: DeserializeOwned>(&self) -> Result<T, Error>

Deserialize the result as JSON.

Example

let result = rpc.view_function(&contract, "get_data", &[], block).await?;
let data: MyData = result.json()?;

pub fn borsh<T: BorshDeserialize>(&self) -> Result<T, Error>

Deserialize the result as Borsh.

Use this for contracts that return Borsh-encoded data instead of JSON.

Example

let result = rpc.view_function(&contract, "get_state", &args, block).await?;
let state: ContractState = result.borsh()?;
