Struct InitializeTransferHookData 

pub struct InitializeTransferHookData<'a> {
    pub authority: Option<&'a Pubkey>,
    pub program_id: &'a Pubkey,
}

Data required to initialize the transfer hook extension, which is used to execute custom logic when transferring tokens.

Fields

authority: Option<&'a Pubkey>

Who has authority to update the program ID. If None, the program ID cannot be modified.

Some(&Pubkey::default()) is analogous to None in this context.

program_id: &'a Pubkey

Program for transfer hook CPI.

Some(&Pubkey::default()) is analogous to None in this context.

Notes

The initialize transfer hook instruction actually takes an optional program ID, where if both the authority and program ID pubkeys are None, then the Token program will revert because at least one of these values must be present. So if you want to initialize the transfer hook extension, this data must be specified.
