Fields

owner_or_delegate: Signer<'info>

The position owner or delegated authority

nft_account: Box<Account<'info, TokenAccount>>

The token account for the tokenized position

tokenized_position_state: AccountLoader<'info, TokenizedPositionState>

Decrease liquidity for this position

factory_state: AccountLoader<'info, FactoryState>

The program account acting as the core liquidity custodian for token holder

pool_state: UncheckedAccount<'info>

Burn liquidity for this pool CHECK: Safety check performed inside function body

core_position_state: UncheckedAccount<'info>

Core program account to store position data CHECK: Safety check performed inside function body

tick_lower_state: UncheckedAccount<'info>

Account to store data for the position’s lower tick CHECK: Safety check performed inside function body

tick_upper_state: UncheckedAccount<'info>

Account to store data for the position’s upper tick CHECK: Safety check performed inside function body

bitmap_lower_state: UncheckedAccount<'info>

Stores init state for the lower tick CHECK: Safety check performed inside function body

bitmap_upper_state: UncheckedAccount<'info>

Stores init state for the upper tick CHECK: Safety check performed inside function body

last_observation_state: UncheckedAccount<'info>

The latest observation state CHECK: Safety check performed inside function body

core_program: Program<'info, CyclosCore>

The core program where liquidity is burned

Trait Implementations

impl<'info> Accounts<'info> for DecreaseLiquidity<'info> where
    'info: 'info, 

fn try_accounts(
    program_id: &Pubkey,
    accounts: &mut &[AccountInfo<'info>],
    ix_data: &[u8],
    __bumps: &mut BTreeMap<String, u8>
) -> Result<Self>

Returns the validated accounts struct. What constitutes “valid” is program dependent. However, users of these types should never have to worry about account substitution attacks. For example, if a program expects a Mint account from the SPL token program in a particular field, then it should be impossible for this method to return Ok if any other account type is given–from the SPL token program or elsewhere.

impl<'info> AccountsExit<'info> for DecreaseLiquidity<'info> where
    'info: 'info, 

fn exit(&self, program_id: &Pubkey) -> Result<()>

program_id is the currently executing program.

impl<'info> ToAccountInfos<'info> for DecreaseLiquidity<'info> where
    'info: 'info, 

fn to_account_infos(&self) -> Vec<AccountInfo<'info>>

impl<'info> ToAccountMetas for DecreaseLiquidity<'info>

fn to_account_metas(&self, is_signer: Option<bool>) -> Vec<AccountMeta>

is_signer is given as an optional override for the signer meta field. This covers the edge case when a program-derived-address needs to relay a transaction from a client to another program but sign the transaction before the relay. The client cannot mark the field as a signer, and so we have to override the is_signer meta field given by the client.
