Estimate energy

The method you must use to estimate energy of a request.

You can set any parameter like method.send()

To estimate a request, you can simply replace send() with estimateV2():

// Example method().send()

const onSend = async () => {
     try {
        const instance = await tronSave.contract().at("...");
        const testSend = await instance.method().send({
             feeLimit: 1e9,
             callValue: 1000000,
             ...
         })
     } catch (err) {
          console.log(err)
     }
}

// With estimateV2()

const onEstimateEnergy = async () => {
     try {
        const instance = await tronSave.contract().at("...");
        const testEstimateEnergy = await instance.method().estimateV2({
             feeLimit: 1e9,
             callValue: 1000000,
             ...
         });
         console.log(testEstimateEnergy);
         //  Response type: {
         //       available_energy: 0,
          //      discount_percent: 0,
          //      total_estimate_energy: 0,
           //     buy_energy_price: 0
        // }
    } catch (err) {
          console.log(err)
     }
}

Result estimateV2()

   {
      available_energy: 976304,
      discount_percent: 80,
      total_estimate_energy: 976304,
      buy_energy_price: 65,
   }

Keys	Type	Description
available_energy	number	The amount of energy that the system can provide for the above request. If it meets 100%, it will return the same amount of energy as estimated.
total_estimate_energy	number	The amount of energy that the system has estimated for the command.
buy_energy_price	number	It is the energy price (SUN) that you can buy the entire amount of energy estimated on the TRONSAVE market.
