/**
 * A plugin that converts snake_case identifiers in the database into
 * camelCase in the JavaScript side.
 *
 * For example let's assume we have a table called `person_table`
 * with columns `first_name` and `last_name` in the database. When
 * using `CamelCasePlugin` we would setup Kysely like this:
 *
 * ```ts
 * import * as Sqlite from 'better-sqlite3'
 * import { CamelCasePlugin, Kysely, SqliteDialect } from 'kysely'
 *
 * interface CamelCasedDatabase {
 *   userMetadata: {
 *     firstName: string
 *     lastName: string
 *   }
 * }
 *
 * const db = new Kysely<CamelCasedDatabase>({
 *   dialect: new SqliteDialect({
 *     database: new Sqlite(':memory:'),
 *   }),
 *   plugins: [new CamelCasePlugin()],
 * })
 *
 * const person = await db.selectFrom('userMetadata')
 *   .where('firstName', '=', 'Arnold')
 *   .select(['firstName', 'lastName'])
 *   .executeTakeFirst()
 *
 * if (person) {
 *   console.log(person.firstName)
 * }
 * ```
 *
 * The generated SQL (SQLite):
 *
 * ```sql
 * select "first_name", "last_name" from "user_metadata" where "first_name" = ?
 * ```
 *
 * As you can see from the example, __everything__ needs to be defined
 * in camelCase in the TypeScript code: table names, columns, schemas,
 * __everything__. When using the `CamelCasePlugin` Kysely works as if
 * the database was defined in camelCase.
 *
 * There are various options you can give to the plugin to modify
 * the way identifiers are converted. See {@link CamelCasePluginOptions}.
 * If those options are not enough, you can override this plugin's
 * `snakeCase` and `camelCase` methods to make the conversion exactly
 * the way you like:
 *
 * ```ts
 * class MyCamelCasePlugin extends CamelCasePlugin {
 *   protected override snakeCase(str: string): string {
 *     // ...
 *
 *     return str
 *   }
 *
 *   protected override camelCase(str: string): string {
 *     // ...
 *
 *     return str
 *   }
 * }
 * ```

     * This is called for each query before it is executed. You can modify the query by
     * transforming its {@link OperationNode} tree provided in {@link PluginTransformQueryArgs.node | args.node}
     * and returning the transformed tree. You'd usually want to use an {@link OperationNodeTransformer}
     * for this.
     *
     * If you need to pass some query-related data between this method and `transformResult` you
     * can use a `WeakMap` with {@link PluginTransformQueryArgs.queryId | args.queryId} as the key:
     *
     * ```ts

     *   RootOperationNode,
     *   UnknownRow
     * } from 'kysely'

     *   // ...
     * }
     * const data = new WeakMap<any, MyData>()
     *
     * const plugin = {
     *   transformQuery(args: PluginTransformQueryArgs): RootOperationNode {
     *     const something: MyData = {}
     *
     *     // ...
     *
     *     data.set(args.queryId, something)
     *
     *     // ...

     *     return args.node
     *   },
     *
     *   async transformResult(args: PluginTransformResultArgs): Promise<QueryResult<UnknownRow>> {
     *     // ...

     *     const something = data.get(args.queryId)

     *     // ...

     *     return args.result
     *   }
     * } satisfies KyselyPlugin
     * ```
     *

     * is not always matched by a call to `transformResult` which would leave orphaned items in the map
     * and cause a memory leak.
     */
