cabal-version: 3.0

-- Created : 29 December 2022

name:
  atomic-counter
version:
  0.1.2.3
synopsis:
  Mutable counters that can be modified with atomic operatinos

description:
  This package defines Counter type that can be safely modified
  concurrently from multiple threads. The type supports only few
  operations, namely read, write, cas (compare and swap), add,
  subtract and a few bitwise ones like or, and xor.

  Most common use case is having a shared counter that multiple
  threads increment. Another potential use case is lightweight locks.
