Processing Instructions

What are Instructions?

Chapter 3: Processing Instructions

Once defined, instructions process data and interact with accounts using the Context struct, which provides access to accounts and program state.

• Key Points:

  • Access accounts via ctx.accounts.

  • Write logic in Rust, leveraging its type safety.

  • Anchor enforces account constraints for security.

• Code Example:

pub fn initialize(ctx: Context<Initialize>) -> Result<()> {
    let my_account = &mut ctx.accounts.my_account;
    my_account.is_initialized = true;
    Ok(())
}

• Interactivity: Simulate running the instruction with different account states and observe how the account data changes.
