#[serde_prefix_all]Expand description
Add #[serde(rename = "prefix_field_name")] or #[serde(alias = "prefix_field_name")] to all fields/variants
of a struct or enum.
Use mode = "rename" (default) to emit #[serde(rename = "...")] or mode = "alias" to emit
#[serde(alias = "...")].
Individual fields/variants can opt-out with #[serde_prefix_all(skip)].
