//! An API suitable for use by a CLI binary.
//!
//! It provides functions and types largely based around strings and integers, as would be expected
//! to be input by a CLI user.  The functions then parse these inputs into the expected Rust types
//! and pass them through to the equivalent API functions defined in the root of the library.
//!
//! # Common Parameters
//!
//! Many of the functions have similar parameters.  Descriptions for these common ones follow:
//!
//! * `maybe_rpc_id` - The JSON-RPC identifier, applied to the request and returned in the response.
//!   If it can be parsed as an `i64` it will be used as a JSON integer. If empty, a random `i64`
//!   will be assigned.  Otherwise the provided string will be used verbatim.
//! * `node_address` - The hostname or IP and port of the server, e.g. `http://127.0.0.1:7777`.
//! * `verbosity_level` - When `1`, the JSON-RPC request will be printed to `stdout` with long
//!   string fields (e.g. hex-formatted raw Wasm bytes) shortened to a string indicating the char
//!   count of the field.  When `verbosity_level` is greater than `1`, the request will be printed
//!   to `stdout` with no abbreviation of long fields.  When `verbosity_level` is `0`, the request
//!   will not be printed to `stdout`.
//! * `maybe_block_id` - Must be a hex-encoded, 32-byte hash digest or a `u64` representing the
//!   [`Block`] height or empty.  If empty, the latest `Block` known on the server will be used.
