Struct Json 

pub struct Json<T>(pub T);

A model field stored as JSON: TEXT on SQLite, JSONB (or JSON, TEXT) on PostgreSQL. Serializes as the value itself, so templates and APIs see the list or object.

use renox::db::Json;

#[derive(Model, serde::Serialize, Default)]
#[model(table = "products")]
struct Product {
    id: i64,
    tags: Json<Vec<String>>, // tags TEXT (SQLite) / tags JSONB (PostgreSQL)
}

let product = Product { tags: Json(vec!["coffee".into()]), ..Default::default() };
assert_eq!(product.tags.len(), 1); // derefs to the Vec
