Struct MintMetadata 

#[repr(C)]
pub struct MintMetadata {
    pub version: u8,
    pub mint_decompressed: bool,
    pub mint: Pubkey,
    pub mint_signer: [u8; 32],
    pub bump: u8,
}

Light Protocol-specific metadata for compressed mints.

Total size: 67 bytes

• version: 1 byte
• mint_decompressed: 1 byte
• mint: 32 bytes
• mint_signer: 32 bytes
• bump: 1 byte

Fields

version: u8

Version for upgradability

mint_decompressed: bool

Whether the compressed mint has been decompressed to a Mint Solana account. When true, the Mint account is the source of truth.

mint: Pubkey

PDA derived from mint_signer, used as seed for the compressed address

mint_signer: [u8; 32]

Signer pubkey used to derive the mint PDA

bump: u8

Bump seed from mint PDA derivation

Implementations

impl MintMetadata

pub fn compressed_address(&self) -> [u8; 32]

Derives the compressed address from mint PDA, MINT_ADDRESS_TREE and LIGHT_TOKEN_PROGRAM_ID

Trait Implementations

impl BorshDeserialize for MintMetadata

where u8: BorshDeserialize, bool: BorshDeserialize, Pubkey: BorshDeserialize, [u8; 32]: 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 MintMetadata

where u8: BorshSerialize, bool: BorshSerialize, Pubkey: BorshSerialize, [u8; 32]: 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 MintMetadata

fn clone(&self) -> MintMetadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MintMetadata

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

Formats the value using the given formatter.

impl Default for MintMetadata

fn default() -> MintMetadata

Returns the “default value” for a type.

impl PartialEq for MintMetadata

fn eq(&self, other: &MintMetadata) -> 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 MintMetadata

type ZeroCopyAt = ZMintMetadata<'a>

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

impl<'a> ZeroCopyNew<'a> for MintMetadata

type ZeroCopyConfig = ()

Configuration type needed to initialize this type

type Output = <MintMetadata 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
