TypeError: 'async_generator' object is not an iterator错误意味着你尝试将一个异步生成器(async_generator)对象当作普通的迭代器来使用。在Python中,异步生成器用于异步地产生值,它们的行为与普通生成器有所不同,不能直接用于需要迭代器的场合。 2. 分析导致此错误的可能原因 错误的使用方式:尝试在同步上下文中使...

V0217: AsyncGenerator objects are not supported The specification states: 25.5 AsyncGenerator Objects An AsyncGenerator object is an instance of an async generator function and conforms to both the AsyncIterator and AsyncIterable interfaces. AsyncGenerator instances directly inherit properties from the o...

This generator-functiongenhas some interesting aspects (lifted from theMDNdocs) : When a generator function is called, its body is not executed right away. Instead it returns an iterator-object which adheres to theiterator protocoli.e. it has anextmethod. ...

Though note that you can in fact convert directly from a stream to an async iterable (and from). This proposal will introduce a toAsync method which will let you go from Iterator<Promise<T>> to AsyncIterator<T> (but it is order-preserving, not based on the order of promises settling)...
