# dictionaries
Benchmarks for dictionary data structures: hash tables, maps, tries,
etc.
The `judy` package was removed from this test suite for instability;
it segfaults the program.
## Running
For all benchmarks:
$ stack bench
For just space:
$ stack bench :space
For just time:
$ stack bench :time
