Account Data

📦 We're going to store data in a Solana account. 📝

Solana accounts are used to store persistent state. This means that the data stays on the blockchain until the account is closed.

In this example, we demonstrate how to:

1. Define a data structure: We create an AddressInfo struct to store a name, house number, street, and city.
2. Calculate required space: We determine how much memory (bytes) the account needs to store our structure.
3. Initialize the account: We allocate the space and write the initial data.

Frameworks covered:

• Anchor: Uses #[account] and #[derive(InitSpace)] to automate space calculation.
• Native: Manually calculates space and uses Borsh for serialization.
• Pinocchio: A lightweight approach to account data management.

Each implementation shows how to handle fixed-size data and strings with maximum lengths.
