pub struct UnificationTable<S>{
    values: S,
}
Expand description

Table of unification keys and their values. You must define a key type K that implements the UnifyKey trait. Unification tables can be used in two-modes:

  • in-place (UnificationTable<InPlace<K>> or InPlaceUnificationTable<K>):
    • This is the standard mutable mode, where the array is modified in place.
    • To do backtracking, you can employ the snapshot and rollback_to methods.
  • persistent (UnificationTable<Persistent<K>> or PersistentUnificationTable<K>):
    • In this mode, we use a persistent vector to store the data, so that cloning the table is an O(1) operation.
    • This implies that ordinary operations are quite a bit slower though.
    • Requires the persistent feature be selected in your Cargo.toml file.

Layout§

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
