invertible: bidirectional arrows, bijective functions, and invariant functors

[ bsd3, composition, control, data, library ] [ Propose Tags ] [ Report a vulnerability ]

Representations and operations for bidirectional arrows (total isomorphisms: an arrow paired with its inverse). Classes for invariant functors and monoidal functors. Includes a number of useful bijections and operations, as well as interoperability with related packages.

Most users will want to import one or more of Data.Invertible qualified, Control.Invertible.Monoidal unqualified, and any additional compatibility modules.

Haskell bidirectional arrows, bijective functions, and invariant functors

Representations and operations for bidirectional arrows (total isomorphisms: an
arrow paired with its inverse).  Classes for invariant functors and monoidal
functors.  Includes a number of useful bijections and operations, as well as
interoperability with related packages.

See also: semigroupoids, TypeCompose, lens, semi-iso, partial-isomorphisms, and
Piso packages.
