/// Builder for creating the RPC router.
///
/// This builder allows you to selectively enable endpoints for the router,
/// and a [`fallback`](RouterBuilder::fallback) route.
///
/// The [`default`](RouterBuilder::default) is to enable [`all`](RouterBuilder::all) routes.
///
/// # Routes
/// Functions that enable routes are separated into 3 groups:
/// - `json_rpc` (enables all of JSON RPC 2.0)
/// - `other_` (e.g. [`other_get_height`](RouterBuilder::other_get_height))
/// - `bin_` (e.g. [`bin_get_blocks`](RouterBuilder::bin_get_blocks))
///
/// For a list of all `monerod` routes, see
/// [here](https://github.com/monero-project/monero/blob/cc73fe71162d564ffda8e549b79a350bca53c454/src/rpc/core_rpc_server.h#L97-L189),
/// or the source file of this type.
///
/// # Aliases
/// Some routes have aliases, such as [`/get_height`](RouterBuilder::other_get_height)
/// and [`/getheight`](RouterBuilder::other_getheight).
///
/// These both route to the same handler function, but they do not enable each other.
///
/// If desired, you can enable `/get_height` but not `/getheight`.
///
/// # Example
/// ```rust
/// use cuprate_rpc_interface::{RouterBuilder, RpcHandlerDummy};
///
/// // Create a router with _only_ `/json_rpc` enabled.
/// let only_json_rpc = RouterBuilder::<RpcHandlerDummy>::new()
/// .json_rpc()
/// .build();
///
/// // Create a router with:
/// // - `/get_outs.bin` enabled
/// // - A fallback enabled
/// let get_outs_bin_and_fallback = RouterBuilder::<RpcHandlerDummy>::new()
/// .bin_get_outs()
/// .fallback()
/// .build();
///
/// // Create a router with all endpoints enabled.
/// let all = RouterBuilder::<RpcHandlerDummy>::new()
/// .all()
/// .build();
/// ```
