This Haskell package provides a data structure of sets that are indexed by potentially multiple indices.

Sets can be created, modified, and queried in various ways.

The package is a variant of the ixset package. The ixset package makes use of run-time type information to find a suitable index on a query, resulting in possible run-time errors when no suitable index exists. In ixset-typed, the types of all indices available or tracked in the type system. Thus, ixset-typed should be safer to use than ixset, but in turn requires more GHC extensions.

At the moment, the two packages are relatively compatible. As a consequence of the more precise types, a few manual tweaks are necessary when switching from one to the other, but the interface is mostly the same.

Changes

0.3.1.1 (2017-08-14)

GHC 8.2 compatibility.

0.3.1 (2016-06-21)

GHC 8.0 compatibility.

0.3 (2014-07-23)

IxSet internals are now more strict
The empty method of Indexable is now called indices and has a slightly different path; to migrate your code, if you were using Template Haskell, you probably do not have to change anything. Otherwise, wherever you have an instance of Indexable that looks like this
```
 instance Indexable MyIndexSet MyType where  -- OLD
   empty = mkEmpty ...
```
change it to
```
 instance Indexable MyIndexSet MyType where  -- NEW
   indices = ixList ...
```
