State for a permissionless, constant-product AMM pool.

Follows the x * y = k model.

Fields

bump: u8

The PDA bump.

token_a_mint: Pubkey

token_b_mint: Pubkey

token_a_vault: Pubkey

token_b_vault: Pubkey

lp_mint: Pubkey

protocol_fee_share: u16

referrer_fee_share: u16

protocol_fee_vault_a: Pubkey

protocol_fee_vault_b: Pubkey

reserves_a: u64

reserves_b: u64

fee_growth_per_lp_token_a: u128

Total fees of token A accrued per LP token.

fee_growth_per_lp_token_b: u128

Total fees of token B accrued per LP token.

price_a_cumulative: u128

The cumulative price of token A in terms of token B.

price_b_cumulative: u128

The cumulative price of token B in terms of token A.

last_update_timestamp: i64

The timestamp of the last update to the reserves and oracle.

last_fee_update_timestamp: i64

price_a_cumulative_last_fee_update: u128

Snapshot of the cumulative price at the last fee update, used for volatility calculation.

Trait Implementations

impl AccountDeserialize for AmmPool

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 AccountSerialize for AmmPool

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

Serializes the account data into writer.

impl BorshDeserialize for AmmPool

where u8: BorshDeserialize, Pubkey: BorshDeserialize, u16: BorshDeserialize, u64: BorshDeserialize, u128: BorshDeserialize, i64: 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 AmmPool

where u8: BorshSerialize, Pubkey: BorshSerialize, u16: BorshSerialize, u64: BorshSerialize, u128: BorshSerialize, i64: 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 AmmPool

fn clone(&self) -> AmmPool

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AmmPool

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

Formats the value using the given formatter.

impl Default for AmmPool

fn default() -> AmmPool

Returns the “default value” for a type.

impl Discriminator for AmmPool

const DISCRIMINATOR: &'static [u8]

Discriminator slice.

impl Owner for AmmPool

fn owner() -> Pubkey
