pqi-0.0.1.0: pqi.cabal

cabal-version: 3.0
name: pqi
version: 0.0.1.0
category: Database, PostgreSQL
synopsis: Driver-agnostic interface to the PostgreSQL libpq API
description:
  @pqi@ reproduces the API surface of the @postgresql-libpq@ package, but
  reifies the connection (and its results) as a type class instead of a single
  concrete type. This lets callers program against one interface and pick an
  adapter at the type level:

  * @pqi-ffi@ — a thin adapter backed by the C @libpq@ library via
    @postgresql-libpq@.

  * @pqi-native@ — a pure-Haskell adapter that speaks the PostgreSQL wire
    protocol directly.

  This package ships only the interface: the typeclasses, types and a couple of connection-independent helpers.
