pub payer: Signer<'info>,
#[account(mut)]
pub my_account: Account<'info, MyAccountData>,
}
#[derive(AnchorSerialize, AnchorDeserialize)]
pub struct MyInstructionData {
pub amount: u64,
}
pub fn process_my_instruction(ctx: Context, data: MyInstructionData) -> Result<()> {
let my_account = &mut ctx.accounts.my_account;
my_account.balance += data.amount;
Ok(())
}
