}

Concurrent state Merkle tree used for public compressed transactions.

Fields

index: u64

Unique index.

rollover_fee: u64

This fee is used for rent for the next account. It accumulates in the account so that once the corresponding Merkle tree account is full it can be rolled over

rollover_threshold: u64

The threshold in percentage points when the account should be rolled over (95 corresponds to 95% filled).

tip: u64

Tip for maintaining the account.

rolledover_slot: u64

The slot when the account was rolled over, a rolled over account should not be written to.

close_threshold: u64

If current slot is greater than rolledover_slot + close_threshold and the account is empty it can be closed.

next_merkle_tree: Pubkey

Public key of the next Merkle tree.

owner: Pubkey

Owner of the Merkle tree.

delegate: Pubkey

Delegate of the Merkle tree. This will be used for program owned Merkle trees.

associated_queue: Pubkey

state_merkle_tree_struct: [u8; 272]

Merkle tree for the transaction state.

state_merkle_tree_filled_subtrees: [u8; 832]

state_merkle_tree_changelog: [u8; 1220800]

state_merkle_tree_roots: [u8; 76800]

state_merkle_tree_canopy: [u8; 65472]

Trait Implementations

impl AccountDeserialize for StateMerkleTreeAccount

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 StateMerkleTreeAccount

where u64: BorshDeserialize, Pubkey: BorshDeserialize, [u8; 272]: BorshDeserialize, [u8; 832]: BorshDeserialize, [u8; 1220800]: BorshDeserialize, [u8; 76800]: BorshDeserialize, [u8; 65472]: 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,
