Subject: Extract Activitypub logic into separate library (#2288)
X-Git-Url: http://these/git/%7B%60%24%7BwebArchiveUrl%7D/%22%7B%7D/%22https:/nerdica.net/readmes/%24%7Bargs.pageFn.jump%20n%7D?a=commitdiff_plain;h=a2a594b7635db2241602be56250f7d9bf992f7b9;p=lemmy.git

Extract Activitypub logic into separate library (#2288)

* Create example for apub lib

* some rewriting of apub lib

* Add LocalInstance struct for apub lib to avoid using Lemmy Settings

* Move ActorType trait to lemmy_apub, because its not needed in library

* Use reqwest_retry instead of custom impl, dont specify timeout on every send()

* Some improvements to example

* Moved inbox handling to library

* bug fixes

* Move context and serde helpers into library

* wip: example changes

* Add lemmy_utils feature to build only LemmyError

* Rename to activitypub_federation

* Remove lemmy_utils dep from activitypub_federation using generic error type

* Finish activitypub example

* Cleanup and fix tests

* Reorganize library files

* Remove ApubObject.to_tombstone()

* Extract activitypub library into separate git repository
