| on the keys of fsts.</p> |
| <p>Set operations include intersection, union, difference and symmetric |
| difference. The result of each set operation is itself a stream that emits |
| pairs of keys and a sequence of each occurrence of that key in the |
| participating streams. This information allows one to perform set |
| operations on fsts and customize how conflicting output values are handled.</p> |
| <p>All set operations work efficiently on an arbitrary number of |
| streams with memory proportional to the number of streams.</p> |
| <p>The algorithmic complexity of all set operations is <code>O(n1 + n2 + n3 + ...)</code> |
| where <code>n1, n2, n3, ...</code> correspond to the number of elements in each |
| stream.</p> |
| <p>The <code>'f</code> lifetime parameter refers to the lifetime of the underlying set.</p> |
