Struct ViewCallBorsh 

pub struct ViewCallBorsh<T> { /* private fields */ }

Query builder for view functions with Borsh deserialization.

Created by calling .borsh() on a ViewCall. This variant deserializes the response as Borsh instead of JSON.

Example

use near_kit::*;
use borsh::BorshDeserialize;

#[derive(BorshDeserialize)]
struct ContractState { count: u64 }

#[derive(borsh::BorshSerialize)]
struct MyArgs { key: u64 }

async fn example() -> Result<(), near_kit::Error> {
    let near = Near::testnet().build();

    // JSON args, Borsh response
    let state: ContractState = near.view("contract.testnet", "get_state")
        .args(serde_json::json!({ "key": "value" }))
        .borsh()
        .await?;

    // Borsh args, Borsh response
    let state: ContractState = near.view("contract.testnet", "get_state")
        .args_borsh(MyArgs { key: 123 })
        .borsh()
        .await?;
    Ok(())
}

Trait Implementations

impl<T: BorshDeserialize + Send + 'static> IntoFuture for ViewCallBorsh<T>

type Output = Result<T, Error>

The output that the future will produce on completion.

type IntoFuture = Pin<Box<dyn Future<Output = <ViewCallBorsh<T> as IntoFuture>::Output> + Send>>

Which kind of future are we turning this into?

fn into_future(self) -> Self::IntoFuture

Creates a future from a value.
