Struct TokenMetadata 

#[repr(C)]
pub struct TokenMetadata {
    pub update_authority: Pubkey,
    pub mint: Pubkey,
    pub name: Vec<u8>,
    pub symbol: Vec<u8>,
    pub uri: Vec<u8>,
    pub additional_metadata: Vec<AdditionalMetadata>,
}

Used for onchain serialization

Fields

update_authority: Pubkey

The authority that can sign to update the metadata None if zero

mint: Pubkey

The associated mint, used to counter spoofing to be sure that metadata belongs to a particular mint

name: Vec<u8>

The longer name of the token

symbol: Vec<u8>

The shortened symbol for the token

uri: Vec<u8>

The URI pointing to richer metadata

additional_metadata: Vec<AdditionalMetadata>

Any additional metadata about the token as key-value pairs. The program must avoid storing the same key twice.

Trait Implementations

impl BorshDeserialize for TokenMetadata

where Pubkey: BorshDeserialize, Vec<u8>: BorshDeserialize, Vec<AdditionalMetadata>: BorshDeserialize,

fn deserialize_reader<R: Read>(reader: &mut R) -> Result<Self, Error>

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.

fn try_from_reader<R>(reader: &mut R) -> Result<Self, Error>

where R: Read,

impl BorshSerialize for TokenMetadata

where Pubkey: BorshSerialize, Vec<u8>: BorshSerialize, Vec<AdditionalMetadata>: BorshSerialize,

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

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

Serialize this instance into a vector of bytes.

impl Clone for TokenMetadata

fn clone(&self) -> TokenMetadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TokenMetadata

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

Formats the value using the given formatter.

impl Hash for TokenMetadata

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for TokenMetadata

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'a> ZeroCopyAt<'a> for TokenMetadata

type ZeroCopyAt = ZTokenMetadata<'a>

fn zero_copy_at( __remaining_bytes: &'a [u8], ) -> Result<(Self::ZeroCopyAt, &'a [u8]), ZeroCopyError>

impl<'a> ZeroCopyNew<'a> for TokenMetadata

type ZeroCopyConfig = TokenMetadataConfig

Configuration type needed to initialize this type

type Output = <TokenMetadata as ZeroCopyAtMut<'a>>::ZeroCopyAtMut

Output type - the mutable zero-copy view of this type

fn byte_len(config: &Self::ZeroCopyConfig) -> Result<usize, ZeroCopyError>

Calculate the byte length needed for this type with the given configuration

fn new_zero_copy( __remaining_bytes: &'a mut [u8], config: Self::ZeroCopyConfig, ) -> Result<(Self::Output, &'a mut [u8]), ZeroCopyError>

Initialize this type in a mutable byte slice with the given configuration
