The default Horus options used by
khepri_projection:new/3
prevent unintentional non-determinism or interaction between processes. It could be useful to have an escape hatch for this, though. For example you might want to callpersistent_term:get/2
andpersistent_term:put/2
to create some lazy value to use in the projection function.This change allows passing in
horus:options()
when creating a projection withkhepri_projection:new/2
. These options are merged with the defaults and passed tohorus:to_standalone_fun/2
.
