Struct near_fetch::Client

pub struct Client { /* private fields */ }

Client that implements exponential retrying and caching of access key nonces.

Implementations

impl Client

pub fn new(rpc_addr: &str) -> Self

Construct a new Client with the given RPC address.

pub fn from_client(client: JsonRpcClient) -> Self

Construct a Client from an existing JsonRpcClient.

pub fn rpc_addr(&self) -> String

The RPC address the client is connected to.

pub async fn send_tx<T: Signer + ExposeAccountId>( &self, signer: &T, receiver_id: &AccountId, actions: Vec<Action> ) -> Result<FinalExecutionOutcomeView>

Send a series of Actions as a SignedTransaction to the network.

pub async fn view<T: Serialize, R: DeserializeOwned>( &self, receiver_id: &AccountId, function_name: &str, args: T ) -> Result<R>

View into a function.

pub async fn fetch_nonce( &self, account_id: &AccountId, public_key: &PublicKey ) -> Result<(Nonce, CryptoHash, BlockHeight)>

Fetches the nonce associated to the account id and public key, which essentially is the access key for the given account ID and public key. Utilize caching underneath to prevent querying for the same access key multiple times.

pub async fn access_key( &self, account_id: &AccountId, public_key: &PublicKey ) -> Result<(AccessKeyView, CryptoHash, BlockHeight)>

Fetches the access key for the given account ID and public key.

pub async fn view_block( &self, block_reference: BlockReference ) -> Result<BlockView>

Fetches the block for this block reference.

pub async fn check_and_invalidate_cache( &self, cache_key: &CacheKey, result: &Result<FinalExecutionOutcomeView, JsonRpcError<RpcTransactionError>> )

pub async fn invalidate_cache(&self, cache_key: &CacheKey)

Trait Implementations

impl Clone for Client

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Client

fn fmt(&self, f: &mut Formatter<'_>) -> Result
