what's the best way to get rid of "Warning: Failure condition of 'send' ignored. Consider using 'transfer' instead."? i have a contract where i need to ignore the result of send() for good reasons

Assign the send transaction to a bool and ignore that variable

A mapping won't cost that much gas if you have less than 100 id check per transaction (estimate)

Could be upto 500

And using Matic ERC721, so gas is not an issue.

Put it on testnet and get an estimate with extreme conditions

Gas limit can be, so better test it out before implementing

Thanks, will do.

That would result in an unused variable warning. I'm trying to get back down to zero warnings after introducing those sends

Return that variable in the function.

I think it'd much rather do something stupid like

successful = sth.send(...);
successful = successful;

than change the function's interface

I'm not looking for any solution. I'm looking for the best solution

Redundant and useless, but works🙃

Like a comment that tells the compiler to skip that check

You cannot ignore compiler warnings. It was proposed, but rejected

Damn :(

If you think about it, it makes sense. You see a warning, there is an urge to remove it. So warnings will help to refactor the code more properly

If you think about it, having 4 compiler warnings bug you at all times for no reason, you're probably a lot slower even just to notice the presence of a 5th one

The first 4 bytes of the hash of its signature w/o any spaces

Know you, if possible work if doesn't know the label without hexa string?

I'm not sure what you're asking. But you can use functionname.selector to get the selector

Wtf!? I'm trying to help someone here and didn't have an internet connection when that message popped up (I'm on a train rn, so losing and gaining a connection all the time but sometimes it's out for 10 minutes)

But since i didn't get banned, you can have this link
