Hancock 2.0.1
Hancock 2.0 adds the notion of parameterization for Hancock's
directory, map, pickle, and stream types. This mechanism reduces
the number of distinct types that a programmer must specify without
sacrificing the data safety gained from Hancock's static and dynamic
type checking. Parameterization can also help with processing
variable-width data.
Hancock 2.0 maps are always keyed by values of type long long.
Such maps use a new mechanism for conveying the legal range
of keys and for tuning their on-disk representations.
Hancock 2.0 introduces a new type, called generative streams, for
streams that do not have a physical representation.
Finally, Hancock 2.0 comes with a small library of stream
types, which facilitate iterating over various combinations of maps.
Version 2.0.1 fixes a performance bug introduced in Hancock 2.0 and
a few other minor bugs.
