This dashboard summarizes the stability levels for all of the public modules of the crate, according to the total number of items at each level in the module and its children (percentages total for std):
stable (18%),
unstable (27%),
experimental (47%),
deprecated (5%),
unmarked (0%)
The counts do not include methods or trait implementations that are visible only through a re-exported type.
