not support json string serialize and deserialize about bson-rust HOT 6 CLOSED

If I understand it correctly, what you want is removing to_json and from_json for BSON? That's impossible. It is necessary for mongo's shell.

BSON to JSON specification is defined here.

from bson-rust.

nope, for example, the web sent param as "{"name":"elton", "female": false}", the web server's handle should use to_bson(&param).to_extended_document() to store into mongodb directly, not convert to json first

from bson-rust.

Why would you say that Bson will convert to JSON first?

from bson-rust.

Ok, I see what you mean. What you want is a wrapper of

let json_str = ...;
let bson = Bson::from_json(&json_str.parse::<Value>().unwrap());

from bson-rust.

I would argue that this is not a real demand. Because it is your responsibility to convert the input string to serde_json::Value, not me.

As you can see in serde_json's document, it also provides

• from_iter
• from_reader
• from_slice
• from_str

for converting inputs to a Value, so I should also provide Bson::from_json_iter, Bson::from_json_reader ... bla bla. No. I don't think so.

In real production code, you must write code like this

let input = ...; // Input value

// **You have to handle this error in your code**
let json = try!(input.parse::<Value>());

// and then generate a valid Bson
let bson = Bson::from_json(json);

// ... #59 value getter
let doc = bson.as_document().unwrap();

// ...

from bson-rust.
