Can I conditionally serde(rename) a field based on what serializer is being used?

#[derive(Debug, Serialize, Deserialize)]
struct Foo {
    // for DynamoDB, name is reserved, so use "foo_name" as the field name
    #[serde(rename = "foo_name")]
    name: String,
}

When I write to DynamoDB, I need to rename the name field. When I serialize as a JSON string, I'd like to not have it named foo_name.

While I could use an intermediate struct, is there another way to conditionalize the rename, so that the JSON string has {"name": "some-name"}?
