## Description
|
|
|
|
This package can be used to manage Switchboard data feed account parsing.
|
|
|
|
Specifically, this package will return the most recent confirmed round result
|
|
from a provided data feed AccountInfo.
|
|
|
|
## Usage
|
|
|
|
### Aggregator
|
|
|
|
```rust
|
|
use switchboard_v2::AggregatorAccountData;
|
|
use std::convert::TryInto;
|
|
|
|
let feed_result = AggregatorAccountData::new(feed_account_info)?.get_result()?;
|
|
|
|
let decimal: f64 = feed_result.try_into()?;
|
|
```
|
|
|
|
### Aggregator History
|
|
|
|
```rust
|
|
use switchboard_v2::AggregatorHistoryBuffer;
|
|
use std::convert::TryInto;
|
|
|
|
let history_buffer = AggregatorHistoryBuffer::new(history_account_info)?;
|
|
let current_timestamp = Clock::get()?.unix_timestamp;
|
|
let one_hour_ago: f64 = history_buffer.lower_bound(current_timestamp - 3600).unwrap().try_into()?;
|
|
```
|
|
|
|
### VRF Account
|
|
|
|
```rust
|
|
use switchboard_v2::VrfAccountData;
|
|
|
|
let vrf = VrfAccountData::new(vrf_account_info)?;
|
|
let result_buffer = vrf.get_result()?;
|
|
if result_buffer == [0u8; 32] {
|
|
msg!("vrf buffer empty");
|
|
return Ok(());
|
|
}
|
|
|
|
let value: &[u128] = bytemuck::cast_slice(&result_buffer[..]);
|
|
let result = value[0] % 256000 as u128;
|
|
```
