CRUD storage pattern Infinite gas error when trying to implement in Remix

Question

I'm trying to implement @robhitchens CRUD storage pattern in solidity, and I'm getting infinate gas costs when I import the library. Not sure where to go from here.

one of them:

Gas requirement of function HitchensUnorderedKeySet.exists(bytes32) high: infinite. If the gas requirement of a function is higher than the block gas limit, it cannot be executed.

pragma solidity ^0.5.1;

import "https://github.com/rob-Hitchens/UnorderedKeySet/blob/master/contracts/HitchensUnorderedKeySet.sol";

contract Filter {

    using HitchensUnorderedKeySetLib for HitchensUnorderedKeySetLib.Set;
    HitchensUnorderedKeySetLib.Set filterSet;

    struct FilterStruct {
        string name;
        string tag;
    }


    mapping(bytes32 => FilterStruct) public filters;

    event LogNewFilter(address sender, bytes32 key, string Filternamename);

    function newFilter(bytes32 key, string memory name) public {
        filterSet.insert(key);
        FilterStruct storage f = filters[key];
        f.name = name;


        emit LogNewFilter(msg.sender, key, name);
    }

}

This "warning" relates to the 'require' conditions that may not be 'true'. It can be safely ignored. Experiment with 'require' in a simple setting to see what I mean.

Hopefully the Remix team will find a way to make the warning more useful, with fewer false positives.

Hope it helps.

P.s. You can silence the high/infinite gas warning in Remix.
