hash-table-rehash-threshold hash-table → rehash-threshold

hash-table — a hash table.

rehash-threshold — a real of type (real 0 1).

Returns the current rehash threshold of hash-table, which is suitable for use in a call to make-hash-table in order to produce a hash table with state corresponding to the current state of the hash-table.

 (setq table (make-hash-table :size 100 :rehash-threshold 0.5)) 
→ #<HASH-TABLE EQL 0/100 2562446> 
 (hash-table-rehash-threshold table) → 0.5

Should signal an error of type type-error if hash-table is not a hash table.
