Is there any way to use this for pre-signing urls sent to clients?

[sebastiangug]

I was hoping to use this to generate a of read URLs on the fly that might not be used, in this case using the built-in presign command in the v3 sdk would make a bit of a dent on the performance side of things.

I came across this but can't seem to quite get the conversion to a presigned url from that request object (or perhaps there's no way since it's not the indended use case).

Have others been succesful in using the library this way?

Is it even possible? can one make a feature request?

Are there known synchronous alternatives?
