How to use the entrypoints.reader.EntryPointsScanner.scan function in entrypoints

def iter_all_epinfo(path=None):
    # Distributions found earlier in path will shadow those with the same name
    # found later. If these distributions used different module names, it may
    # actually be possible to import both, but in most cases this shadowing
    # will be correct. pkg_resources does something similar.

    for location_ep in EntryPointsScanner().scan(path):
