custom api methods for drivers.

[ivanjeremic]

It would be nice if we could create custom methods for custom and existing drivers to add custom functionallity.

const myStorageDriver = defineDriver((options) => {

  const getInstance = () => { // myInstance };
 
  const extendDriver = options.extendDriver(getInstance);
  
  return {
    name: "my-custom-driver",
    options,
    async hasItem(key, _opts) {},
    async getItem(key, _opts) {},
    async setItem(key, value, _opts) {},
    async removeItem(key, _opts) {},
    async getKeys(base, _opts) {},
    async clear(base, _opts) {},
    async dispose() {},
    async watch(callback) {},
    {...extendDriver}
  };
});

const storage = createStorage({
  driver: memoryDriver({
    extendDriver: (instance) => ({
     myCustomMehod() {
       // do something with the instance
       return dataFromSomeCustomKvOperation;
     };
  });
  }), 
});
