Basic usage of MinHash: create two MinHash instances, update with byte strings, and compute Jaccard similarity.

from rensa import MinHash m1 = MinHash() m2 = MinHash() for d in ["hello", "world"]: m1.update(d.encode('utf-8')) for d in ["hello", "rust"]: m2.update(d.encode('utf-8')) print("Jaccard similarity:", m1.jaccard(m2))

Debug

Known issues

gotchaInput to update() must be bytes, not strings. Forgetting to encode strings leads to TypeError.

fix

Use .encode('utf-8') or pass bytes directly.

affects: all

gotchaMinHash signatures are not serializable directly. The library does not provide a built-in serialization method as of 0.4.0.

fix

Manually extract signature via m.signature (a list) and serialize with e.g. pickle or JSON (but note performance).

affects: 0.4.0

deprecatedIf you previously used rensa from a different source (e.g., a fork), note that the API is minimal and may change in future versions.

fix

Check the latest documentation on GitHub for any API changes.

affects: <0.4.0
