//! Batch and cache database queries or other potentially expensive data
//! lookups. The main motivation for this library is to solve the
//! "N + 1" query problem seen in GraphQL and elsewhere. This library takes
//! heavy influence from the GraphQL Foundation's [DataLoader](https://github.com/graphql/dataloader).
//!
//! The most common entrypoints to this library are the [`Batcher`](struct.Batcher.html)
//! type (used to queue and load data in batches) and the [`Fetcher`](trait.Fetcher.html)
//! trait (used by [`Batcher`](struct.Batcher.html)s to actually retrieve
//! the data).
