+/**
+ * A helper type that allows inferring a select/insert/update/delete query's result
+ * type from a query builder or compiled query.
+ *
+ * ### Examples
+ *
+ * Infer a query builder's result type:
+ *
+ * ```ts
+ * import { InferResult } from 'kysely'
+ *
+ * const query = db
+ *   .selectFrom('person')
+ *   .innerJoin('pet', 'pet.owner_id', 'person.id')
+ *   .select(['person.first_name', 'pet.name'])
+ *
+ * type QueryResult = InferResult<typeof query> // { first_name: string; name: string; }[]
+ * ```
+ *
+ * Infer a compiled query's result type:
+ *
+ * ```ts
+ * import { InferResult } from 'kysely'
+ *
+ * const compiledQuery = db
+ *   .insertInto('person')
+ *   .values({
+ *     first_name: 'Foo',
+ *     last_name: 'Barson',
+ *     gender: 'other',
+ *     age: 15,
+ *   })
+ *   .returningAll()
+ *   .compile()
+ *
+ * type QueryResult = InferResult<typeof compiledQuery> // Selectable<Person>[]
+ * ```
