from_value in Deserializer

[andrewbaxter]

I'm deserializing to Value and doing some merging, then deserializing again into a structure. I was using serde_json::from_value for this but I want to use path-to-error and it seems like Deserializer has no from_value method.

Would it be reasonable to add this? For now I can workaround by re-serializing first.

Does the serde_path_to_errorcrate fulfill your needs?

I'll quote dtolnay #173 (comment):

Here is the library: https://github.com/dtolnay/path-to-error. You can use it to wrap any Deserializer and find out where an error occurs.

Note that Value (and &Value) itself implements serde's Deserializer trait.
