Soroban Smart Contract

A Smart contract will be written to support storing data based on a <Persistent> strategy.

// Pseudocode 


#[contracttype]
pub enum DataKey {
    Favorite(Address),
}

#[contract]
pub struct FavoriteContract;

#[contractimpl]
impl DominiumHashWriter {
    // this function takes the hash of a document and stores it.  
    pub fn storeHash(data:Int32, String:docName, env:Env -> void {
        env.storage().persistent().set(&key, &data);
 
    }

    // This fuction 
    pub fn UpdateHash(env: Env,String:DocName, Int32 hash, user: Address) -> u64 {
      
        if let Some(data) = env.storage().persistent().get(&key) {
            fave
        } else {
            0
        }
    }
}
