Description

I try to keep track of non-exportable object examples in the Non-Exportable Objects vignette. Let's use this issue to gather additional examples of packages and object classes that cannot be exported to another R process or saved to be used in another R session.

Additional examples:

Package raster, e.g. raster::writeStart() (https://stackoverflow.com/questions/65148384)
Package xboost, e.g. xgboost::xgb.DMatrix() (https://stackoverflow.com/questions/65136945/issues-with-running-xgboost-in-multiple-r-processes)
Package terra, e.g. SpatRaster and SpatVector (https://stackoverflow.com/questions/67445883/terra-package-returns-error-when-try-to-run-parallel-operations). Mention also terra::wrap() for "marshalling"
Bioconductor package ShortRead, e.g. 'FastqStreamerList' (https://support.bioconductor.org/p/9135851/)

Research direction: Check the current state of the Non Exportable Objects vignette (https://cran.r project.org/web/packages/future/vignettes/future 4 non exportable objects.html) to see if the examples listed (raster, xgboost, terra, ShortRead) are already included. If not, add them. Also search for additional packages with non exportable objects and propose them in the issue.
