Struct CallFunctionBuilder 

pub struct CallFunctionBuilder {
    contract: AccountId,
    method_name: String,
    args: Vec<u8>,
}

Fields

contract: AccountId

method_name: String

args: Vec<u8>

Implementations

impl CallFunctionBuilder

pub fn read_only<Response: Send + Sync + DeserializeOwned>( self, ) -> RequestBuilder<CallResultHandler<Response>>

Prepares a read-only query that doesn’t require a signing transaction.

Example

use near_api::*;

let balance: Data<u64> = Contract("some_contract.testnet".parse()?).call_function("get_balance", ())?.read_only().fetch_from_testnet().await?;
println!("Balance: {:?}", balance);

let balance_at_block: Data<u64> = Contract("some_contract.testnet".parse()?).call_function("get_balance", ())?.read_only().at(Reference::AtBlock(1000000)).fetch_from_testnet().await?;
println!("Balance at block 1000000: {:?}", balance_at_block);

pub fn read_only_borsh<Response: Send + Sync + BorshDeserialize>( self, ) -> RequestBuilder<CallResultBorshHandler<Response>>

Prepares a read-only query that deserializes the response using Borsh instead of JSON.

This method is useful when the contract returns Borsh-encoded data instead of JSON.

Example

use near_api::*;

let value: Data<u64> = Contract("some_contract.testnet".parse()?)
    .call_function("get_number", ())?
    .read_only_borsh()
    .fetch_from_testnet()
    .await?;
println!("Value: {:?}", value);

pub fn transaction(self) -> ContractTransactBuilder

Prepares a transaction that will call a contract function leading to a state change.

This will require a signer to be provided and gas to be paid.
