No project description provided

swh-digestmap Python binding

## Use

from swh.digestmap import DigestMap
digestmap = DigestMap("dest_folder")
digestmap.sha1_from_swhid("swh:1:cnt:0000000000000000000000000000000000000004")

found = digestmap.content_get([b"0000000000000000000000000000000000000004"], algo="sha1_git")
if found and found[0]:
    hashes_dict = found[0].hashes()

## Use as a Software Heritage storage backend

The Python package will register digestmap as a Software Heritage storage backend. However it only partially implements content_get: returned content objects should only be used to fetch .hashes() as in the example above. Note that the returned dict will only contain hashes known to the digestmap, sha1 and sha1_git. If you are not bothered by these limitations (for example, you're using swh-fuse) It can be configured as such:

storage:
  cls: digestmap
  path: "/path/to/digestmap/folder"

## Develop

pip install -r requirements-swh.txt
pip install -r requirements-tests.txt
cd pyo3/
pip install .
pytest

We test via pytest because the DigestMap binding needs a Python able to import swh.model.model.

Package with cibuildwheel pyo3 from the repository's root.
