I couldn't find any implementation info on Twitter's API "cursoring" pagination system https://developer.twitter.com/en/docs/basics/cursoring. I'd like to replicate it for #Friendica 's #API since we emulate their API, but so far I only have the "next_cursor" feature, no idea how to compute the "previous_cursor" value.

I'm looking for either a high-level explanation of this system that doesn't seem to rely on the usual "max_id"/'since_id" boundaries, or an actual implementation of it.

Thanks!
