Circular buffer which is built over Item and [Map]. Might be useful to store time series data in contracts.

Example

use cosmwasm_std::testing::MockStorage;
use astroport_circular_buffer::{BufferManager, CircularBuffer};

const CIRCULAR_BUFFER: CircularBuffer<u128> = CircularBuffer::new("buffer_state", "buffer");

let mut store = MockStorage::new();
BufferManager::init(&mut store, CIRCULAR_BUFFER, 10).unwrap();
let mut buffer = BufferManager::new(&store, CIRCULAR_BUFFER).unwrap();

let data = (1..=10u128).collect::<Vec<_>>();
buffer.push_many(&data);
buffer.commit(&mut store).unwrap();

let values = buffer.read(&store, 0u32..=9, true).unwrap();
let all_values = buffer.read_all(&store).unwrap();
