func ParseFullPositionFromBytes 

func ParseFullPositionFromBytes(key, value []byte) (types.FullPositionByOwnerResult, error)

ParseFullPositionFromBytes parses a full position from key and value bytes. Returns a struct containing the pool id, lower tick, upper tick, frozen until, and liquidity associated with the position. Returns an error if the key or value is not found. Returns an error if fails to parse either.

func ParsePositionFromBz 

func ParsePositionFromBz(bz []byte) (position model.Position, err error)

ParsePositionFromBz parses a position from a byte array. Returns a struct containing the liquidity associated with the position. Returns an error if the byte array is empty. Returns an error if fails to parse.

Types

type Keeper 

type Keeper struct {
	// contains filtered or unexported fields
}

func NewKeeper 

func NewKeeper(cdc codec.BinaryCodec, storeKey sdk.StoreKey, bankKeeper types.BankKeeper, paramSpace paramtypes.Subspace) *Keeper

func (Keeper) CalcInAmtGivenOut 

func (k Keeper) CalcInAmtGivenOut(
	ctx sdk.Context,
	poolI poolmanagertypes.PoolI,
	tokenOut sdk.Coin,
	tokenInDenom string,
	swapFee sdk.Dec,
) (tokenIn sdk.Coin, err error)

func (Keeper) CalcOutAmtGivenIn 

func (k Keeper) CalcOutAmtGivenIn(
	ctx sdk.Context,
	poolI poolmanagertypes.PoolI,
	tokenIn sdk.Coin,
	tokenOutDenom string,

func (Keeper) CreatePosition 

func (k Keeper) CreatePosition(ctx sdk.Context, poolId uint64, owner sdk.AccAddress, amount0Desired, amount1Desired, amount0Min, amount1Min sdk.Int, lowerTick, upperTick int64, frozenUntil time.Time) (sdk.Int, sdk.Int, sdk.Dec, error)

CreatePosition creates a concentrated liquidity position in range between lowerTick and upperTick in a given `PoolId with the desired amount of each token. Since LPs are only allowed to provide liquidity proportional to the existing reserves, the actual amount of tokens used might differ from requested. As a result, LPs may also provide the minimum amount of each token to be used so that the system fails to create position if the desired amounts cannot be satisfied. On success, returns an actual amount of each token used and liquidity created. Returns error if: - the provided ticks are out of range / invalid - the pool provided does not exist - the liquidity delta is zero - the amount0 or amount1 returned from the position update is less than the given minimums - the pool or user does not have enough tokens to satisfy the requested amount

func (Keeper) ExportGenesis

GetPerTickLiquidityDepthFromRange uses the given lower tick and upper tick, iterates over ticks, creates and returns LiquidityDepth array. LiquidityNet from the tick is used to indicate liquidity depths.

func (Keeper) GetPool 

func (k Keeper) GetPool(ctx sdk.Context, poolId uint64) (poolmanagertypes.PoolI, error)

GetPool returns a pool with a given id.

func (Keeper) GetPosition 

func (k Keeper) GetPosition(ctx sdk.Context, poolId uint64, owner sdk.AccAddress, lowerTick, upperTick int64, frozenUntil time.Time) (*model.Position, error)

GetPosition checks if a position exists at the provided upper and lower ticks and frozenUntil time for the given owner. Returns position if found.

func (Keeper) GetUserPositions 

func (k Keeper) GetUserPositions(ctx sdk.Context, addr sdk.AccAddress) ([]types.FullPositionByOwnerResult, error)

GetUserPositions gets all the existing user positions across many pools.
