#[derive(Store)]
{
    // Attributes available to this derive:
    #[store]
    #[key]
    #[index]
    #[unique_index]
    #[migrate_from]
    #[model_name]
}

Derives the Store trait for a struct, generating methods for CRUD operations in TiKV.

This macro will generate the following methods:

• load: Loads an instance from TiKV.
• save: Saves the instance to TiKV.
• delete: Deletes the instance from TiKV.
• by_<field>: For each indexed field, generates a method to find an instance by that field.
• set_<field>: For each field, generates a method to update that field.

Attributes

• #[key]: Marks a field as the primary key. Required on exactly one field.
• #[index]: Marks a field as indexed, allowing efficient lookups.

Example

use ergokv::Store;
use serde::{Serialize, Deserialize};
use uuid::Uuid;

#[derive(Store, Serialize, Deserialize)]
struct User {
    #[key]
    id: Uuid,
    #[index]
    username: String,
    email: String,
}
