_getSlot

function _getSlot() internal pure returns (uint256)

Returns storage slot to use when fetching storage relevant to library

_getStorage

function _getStorage() internal pure returns (struct IFeeTiers.FeeTiersStorage s)

Returns storage pointer for storage struct in diamond contract, at defined slot

_checkFeeTierUpdateValid

function _checkFeeTierUpdateValid(uint256 _index, struct IFeeTiers.FeeTier _feeTier, struct IFeeTiers.FeeTier[8] _feeTiers) internal view

Checks validity of a single fee tier update (feeMultiplier: descending, pointsThreshold: ascending, no gap)

Parameters

Name	Type	Description
_index	uint256	index of the fee tier that was updated
_feeTier	IFeeTiers.FeeTier	fee tier new value
_feeTiers	IFeeTiers.FeeTier[8]	all fee tiers

_getCurrentDay

function _getCurrentDay() internal view returns (uint32)

Get current day (index of mapping traderDailyInfo)

_claimUnclaimedPoints

function _claimUnclaimedPoints(address _trader) internal

Claims unclaimed points for a trader and adds them to the daily points for the current day. In the event that it's the first points update for the trader, backdates points to yesterday so the tier discount becomes immediate.
