Struct AmmPosition 

pub struct AmmPosition {
    pub pool: Pubkey,
    pub owner: Pubkey,
    pub lp_token_amount: u64,
    pub fee_growth_snapshot_a: u128,

}

Represents a user’s liquidity position in a specific AMM pool.

Fields

pool: Pubkey

The AMM pool this position belongs to.

owner: Pubkey

The owner of this position.

lp_token_amount: u64

The number of LP tokens this position represents.

fee_growth_snapshot_a: u128

Snapshot of the pool’s fee growth per LP token for token A.

fee_growth_snapshot_b: u128

Snapshot of the pool’s fee growth per LP token for token B.

fee_preference: FeePreference

The user’s chosen strategy for handling accrued fees.

Trait Implementations

impl AccountDeserialize for AmmPosition

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 AmmPosition

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

Serializes the account data into writer.

impl BorshDeserialize for AmmPosition

where Pubkey: BorshDeserialize, u64: BorshDeserialize, u128: BorshDeserialize, FeePreference: 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 AmmPosition

where Pubkey: BorshSerialize, u64: BorshSerialize, u128: BorshSerialize, FeePreference: 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 AmmPosition

fn clone(&self) -> AmmPosition

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AmmPosition

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

Formats the value using the given formatter.

impl Default for AmmPosition

fn default() -> AmmPosition

Returns the “default value” for a type.

impl Discriminator for AmmPosition

const DISCRIMINATOR: &'static [u8]

Discriminator slice.

impl Owner for AmmPosition

fn owner() -> Pubkey
