Struct mpl_token_metadata::state::Edition

#[repr(C)]
pub struct Edition {
    pub key: Key,
    pub parent: Pubkey,
    pub edition: u64,
}

All Editions should never have a supply greater than 1. To enforce this, a transfer mint authority instruction will happen when a normal token is turned into an Edition, and in order for a Metadata update authority to do this transaction they will also need to sign the transaction as the Mint authority.

Fields

key: Key

parent: Pubkey

Points at MasterEdition struct

edition: u64

Starting at 0 for master record, this is incremented for each edition minted.

Trait Implementations

impl BorshDeserialize for Edition where
    Key: BorshDeserialize,
    Pubkey: BorshDeserialize,
    u64: BorshDeserialize, 

fn deserialize(buf: &mut &[u8]) -> Result<Self, Error>

Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes.

fn try_from_slice(v: &[u8]) -> Result<Self, Error>

Deserialize this instance from a slice of bytes.

impl BorshSerialize for Edition where
    Key: BorshSerialize,
    Pubkey: BorshSerialize,
    u64: BorshSerialize, 

fn serialize<W: Write>(&self, writer: &mut W) -> Result<(), Error>

fn try_to_vec(&self) -> Result<Vec<u8, Global>, Error>

Serialize this instance into a vector of bytes.

impl Clone for Edition

fn clone(&self) -> Edition

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Edition

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Edition

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq<Edition> for Edition

fn eq(&self, other: &Edition) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Edition) -> bool

This method tests for !=.

impl TokenMetadataAccount for Edition

fn key() -> Key

fn size() -> usize

fn pad_length(buf: &mut Vec<u8>) -> Result<(), MetadataError>

fn safe_deserialize<T: BorshDeserialize>(data: &[u8]) -> Result<T, BorshError>

fn from_account_info<T: BorshDeserialize>(
    a: &AccountInfo<'_>
) -> Result<T, ProgramError>
