Fastcounter is an Apache 2.0 licensed fast counter library written in Python.

It aims at implementing fast incremental integer with different trade-offs on

performance depending on your use case.

It provides 3 classes:

- `Counter`, a simple integer counter that does not support any concurrency.

- `FastWriteCounter`, a counter that is thread-safe and is faster at writing

  than reading.

- `FastReadCounter`, a counter that is thread-safe and is faster at reading

  than writing.

Example::

  import fastcounter

  counter = fastcounter.Counter()

  counter.value # returns 1

  counter.increment()

  counter.value # returns 2

  counter.increment(10)

  counter.value # returns 12
