This change completes the migration started in #184 which moved functions that acted on the tree structure from
khepri_machine
tokhepri_tree
. With this change, the tree structure can be created and modified without interacting with the machine state. The implementation ofinsert_or_update_node/5
is extracted tokhepri_tree
without changes except that the creation of side-effects and the reorganizing of the return value now live separately inkhepri_machine
.This also allows us to remove a few function exports from
khepri_tree
which were either being called byinsert_or_update_node/5
or were only used internally tokhepri_tree
.
