Known issues

breakingVersion 1.2.0 added type hints; if you were relying on dynamic attribute access or duck typing, your code may break under strict type checkers.

fix

Update your code to match the type signatures. For example, `increment()` now returns `None` explicitly.

affects: >=1.2.0

deprecatedThe `Counter` base class (if exists) is deprecated in favor of `FastWriteCounter` and `FastReadCounter`.

fix

Replace `from fastcounter import Counter` with `from fastcounter import FastWriteCounter` (or FastReadCounter) and adjust usage accordingly.

affects: >=1.0.0

gotcha`FastReadCounter` does not support `increment()`; it only provides `value()`. Trying to call `increment()` will raise an AttributeError.

fix

Ensure you import the correct counter type: use `FastWriteCounter` for counting operations, `FastReadCounter` for read-only access.

affects: all

Errors

Common errors & fixes

AttributeError: 'FastReadCounter' object has no attribute 'increment'

Using FastReadCounter in a context where incrementing is needed.

fix

Replace `FastReadCounter` with `FastWriteCounter`.

ImportError: cannot import name 'Counter' from 'fastcounter'

The module was renamed or removed. There is no `Counter` in fastcounter.

fix

Use `from fastcounter import FastWriteCounter` or `FastReadCounter`.
