generic-pool

An example of generic data type, providing different types of pool. We can implement new type of pool without do migrating.

Step 1 - Deploy contract with the single pool

Comment the declaration of ComplexPool in enum Pool and the related function

#[derive(BorshSerialize, BorshDeserialize, Debug)]
pub enum Pool {
    SimplePool(SimplePool),
    // Comment this line for the first deployment
    // ComplexPool(ComplexPool),
}

    // Comment this function for the first deployment
    // pub fn create_complex_pool(&mut self) {
    //     let pool_id = self.pools.len() + 1;
    //     self.pools.insert(&pool_id, &Pool::ComplexPool(ComplexPool {prop_b: pool_id as u32}));
    // }

Build and deploy contract

build.sh
deploy.sh 

Create a simple pool

near call dev-1647959336462-77896213135645 create_simple_pool --accountId  dev-1647959336462-77896213135645

View pools

Step 2 - Add the complex pool and redeploy

Uncomment two block of code above & redeploy
