Struct InitializeMetadataPointerData 

pub struct InitializeMetadataPointerData<'a> {
    pub authority: Option<&'a Pubkey>,
    pub metadata: &'a Pubkey,
}

Data required to initialize the metadata pointer extension, which is used to add descriptive information to a mint.

Fields

authority: Option<&'a Pubkey>

Who has authority to update the metadata pointer. If None, the metadata cannot be modified.

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

metadata: &'a Pubkey

Where the metadata is stored.

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

Notes

The initialize metadata pointer instruction actually takes an optional metadata account, where if both the authority and metadata 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 metadata pointer, this data must be specified.
