Enum MintExtension 

pub enum MintExtension<'a> {
    TransferFeeConfig {
        authority: Option<&'a Address>,
        withdraw_authority: Option<&'a Address>,
        basis_points: u16,
        maximum_fee: u64,
    },
    MintCloseAuthority(Option<&'a Address>),
    NonTransferable,
    PermanentDelegate(&'a Address),
    TransferHook {
        authority: Option<&'a Address>,

    },
    MetadataPointer {
        authority: Option<&'a Address>,
        metadata_address: Option<&'a Address>,
    },
}

Fixed-size mint extensions supported by MintPlan.

Extension authorities and hook/metadata addresses use Token-2022’s nullable address encoding where applicable. Some(zero_address) is rejected for those fields, rather than silently being interpreted as None.

Implementations

impl MintExtension<'_>

pub const fn extension_type(&self) -> u16

Token-2022’s TLV extension discriminator (not an instruction tag).

pub fn instruction_data(&self) -> Result<MintInstructionData, ProgramError>

Canonical instruction bytes, also usable by off-chain instruction builders.

Trait Implementations

impl<'a> Clone for MintExtension<'a>

fn clone(&self) -> Self
