Fcf.Data.MapC

Fcf.Data.MapC

MapC provides an interface to mapping keys to values, which is similar to that given by the containers-package. Note that the this module still misses some of the methods that can be found in containers. If you need some, please do open up an issue or better, make a PR.

Many of the examples are from containers-package.

We call this MapC because name Map is reserved to the map-function in Fcf-package. The internal representation is type-level list. We hope that one day the internal representation is based on balanced trees similar to the one used in the containers.

MapC type

data MapC k v

A type corresponding to Map in the containers. We call this MapC because name Map is reserved to the map-function in Fcf-package.

The representation is based on type-level lists. Please, do not use that fact but rather use the exposed API. (We hope to change the internal data type to balanced tree similar to the one used in containers. See TODO.md.)
