用于serde_json::Value以外类型的Stream反序列化器 、、 这些对象中的每一个都具有与其他对象相同的字段(即,我可以使用单个struct轻松地表示所有这些对象)。由于JSON字符串中有几个这样的对象,我认为我应该使用serde_json::StreamDeserializer,尽管我对Rust和serde比较陌生,所以如果这不是正确的方法,请指出正确...

JSON is a ubiquitous open-standard format that uses human-readable text to transmit data objects consisting of key-value pairs. {"name":"John Doe","age":43,"address": {"street":"10 Downing Street","city":"London"},"phones": ["+44 1234567","+44 2345678"] } ...
