    //! Light client logic and implementation.
    //!
    //! A "light" client stores very little chain-related data locally
    //! unlike a full node, which stores all blocks, headers, receipts, and more.
    //!
    //! This enables the client to have a much lower resource footprint in
    //! exchange for the cost of having to ask the network for state data
    //! while responding to queries. This makes a light client unsuitable for
    //! low-latency applications, but perfectly suitable for simple everyday
    //! use-cases like sending transactions from a personal account.
    //!
    //! The light client performs a header-only sync, doing verification and pruning
    //! historical blocks. Upon pruning, batches of 2048 blocks have a number => hash
    //! mapping sealed into "canonical hash tries" which can later be used to verify
    //! historical block queries from peers.

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
