CircularVector class
Circular vector uses a single buffer to capture a stream of values overwriting the oldest value on add.
This supports adding to the ‘head’ or ’tail’ and will grow the buffer to match a configured capacity.
Signature
export declare class CircularVector<T = any> extends FunctionalVector<T> implements MutableVector<T>
Import
import { CircularVector } from '@grafana/data';
