//! Once a `TimestampOracle` is created, there will be two futures running in a background working
//! thread created automatically. The `get_timestamp` method creates a oneshot channel whose
//! transmitter is served as a `TimestampRequest`. `TimestampRequest`s are sent to the working
//! thread through a bounded multi-producer, single-consumer channel. The first future tries to
//! exhaust the channel to get as many requests as possible and sends a single `TsoRequest` to the
//! PD server. The other future receives `TsoResponse`s from the PD server and allocates timestamps
//! for the requests.
