Implementations

impl MerkleTreeMetadata

pub fn init( &mut self, access_metadata: AccessMetadata, rollover_metadata: RolloverMetadata, associated_queue: Pubkey, )

Trait Implementations

impl AccountDeserialize for MerkleTreeMetadata

fn try_deserialize(buf: &mut &[u8]) -> Result<Self>

Deserializes previously initialized account data. Should fail for all uninitialized accounts, where the bytes are zeroed. Implementations should be unique to a particular account type so that one can never successfully deserialize the data of one account type into another. For example, if the SPL token program were to implement this trait, it should be impossible to deserialize a Mint account into a token Account.

fn try_deserialize_unchecked(buf: &mut &[u8]) -> Result<Self>

Deserializes account data without checking the account discriminator. This should only be used on account initialization, when the bytes of the account are zeroed.

impl BorshDeserialize for MerkleTreeMetadata

where AccessMetadata: BorshDeserialize, RolloverMetadata: BorshDeserialize, Pubkey: 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 Clone for MerkleTreeMetadata

fn clone(&self) -> MerkleTreeMetadata

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MerkleTreeMetadata

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

Formats the value using the given formatter.

impl Default for MerkleTreeMetadata

fn default() -> MerkleTreeMetadata

Returns the “default value” for a type.

impl Discriminator for MerkleTreeMetadata

const DISCRIMINATOR: [u8; 8] = _

fn discriminator() -> [u8; 8]

impl Owner for MerkleTreeMetadata

fn owner() -> Pubkey

impl PartialEq for MerkleTreeMetadata

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

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

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

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

impl Zeroable for MerkleTreeMetadata

fn zeroed() -> Self

Calls zeroed.

impl Copy for MerkleTreeMetadata

impl Pod for MerkleTreeMetadata

impl StructuralPartialEq for MerkleTreeMetadata

impl ZeroCopy for MerkleTreeMetadata
