amber-api 2.1.0

//! Example: Get previous, current, and next price intervals for a site.
//!
//! This example demonstrates how to retrieve previous, current, and future
//! price intervals for a site using the `previous` and `next` parameters.
//!
//! # Prerequisites
//!
//! Set your API key in the `AMBER_API_KEY` environment variable and ensure you
//! have at least one site.
//!
//! # Run this example
//!
//! ```console
//! cargo run --example current_prices_complete
//! ```
