You can use different annotations from serde_with to make your example work. The problem how you used serde_with::json::nested is that it converts the whole HashMap into a String, which fails, because the keys do not serialize as strings. If you apply the attribute only to the key part, it works.

You can't skip fields with Bincode.

Bincode is not self-describing so if you skip a field it can't tell if it is None or if it should continue parsing the rest of the input.

Just remove #[skip_serializing_none].

This is a limitation of serde's design. The Deserialize and Serialize implementations are intentionally separated from the Serializer and Deserializer implementations, which gives great flexibility and convenience when choosing different formats and swapping them out. Unfortunately, it means it is isn't possible to individually fine-tune your Deserialize and Serialize implementations for different formats.

The way I have done this before is to duplicate the data types so that I can configure them for each format, and then provide a zero-cost conversion between them.

JSON from rocket_contrib is a convenience, but not essential. You can still parse the JSON yourself from the raw body data with serde (following example is done with async Rocket). This may bypass any issues with headers:

How to get serde_with::nested::json dependency imported properly

I'm trying to use the setup as outlined in the serde_with docs here to deserialize nested json into my struct: https://docs.rs/serde_with/1.4.0/serde_with/json/nested/index.html

After a few tries Cargo.toml file looks like:

ANSWER

Answered 2020-May-23 at 05:06

In your example the module serde_with is not optional and must provide the feature json.

Replace

serde_with = { version = "1.4.0", optional = true}

with

serde_with = { version = "1.4.0", features = ["json"]}
