/**
 * This package contains types that describe the [methods](https://solana.com/docs/rpc/http) of the
 * Solana JSON RPC API, and utilities for creating a {@link RpcApi} implementation with sensible
 * defaults. It can be used standalone, but it is also exported as part of Kit
 * [`@solana/kit`](https://github.com/anza-xyz/kit/tree/main/packages/kit).
 *
 * @example
 * Each RPC method is described in terms of a TypeScript type of the following form:
 *
 * ```ts
 * type ExampleApi = {
 *     getSomething(address: Address): Something;
 * };
 * ```
 *
 * A {@link RpcApi} that implements `ExampleApi` will ultimately expose its defined methods on any
 * {@link Rpc} that uses it.
 *
 * ```ts
 * const rpc: Rpc<ExampleApi> = createExampleRpc(/* ... *\/);
 * const something: Something = await rpc.getSomething(address('95DpK3y3GF7U8s1k4EvZ7xqyeCkhsHeZaE97iZpHUGMN')).send();
 * ```
