diesel_json

Provides a wrapper diesel_json::Json type that can be directly used to wrap serde serializable, deserializable structures and recognize them as queryable, insertable JsonB fields.

Getting started

Wrap data structures into diesel_json::Json type.

```rust

[derive(Serialize, Deserialize)]

struct ComplexStruct { // ... }

[derive(Serialize, Deserialize, Queryable, Insertable, AsChangeset, Identifiable)]

struct ExampleTable { // ... // Field that will be stored in Jsonb format jsonbfield: dieseljson::Json, // ... } ```

Json type provides new function for object initialization, implements Deref, DerefMut, AsRef, AsMut that maps data access directly to underlying data.

Why should I use this library?

Without wrapper type for each unique type you store as JsonB field you would need to use serde_json::Value directly or implement your own implementation for following traits: rust impl<T> FromSql<sql_types::JsonB, Pg> for Json<T> {} impl<T> ToSql<sql_types::JsonB, Pg> for Json<T> {}

TODO:

• [ ] Support not only JsonB, but also Json postgres type
• [ ] Support more database drivers
  • [x] PostgreSQL
  • [ ] MySql
  • [ ] SQLite
• [ ] Improve testing of library
