FAQ

Why the name pysistence?

The project is named pysistence because most of the data structures it implements are persistent. This doesn't mean persistent in the sense that they are stored in a database or the file system. Rather, it means the data structures may only be modified by copying. Where possible, these data structures will re-use existing implementations without copying everything.

Where can I learn more about persistent data structures?
