Function faiss::index::index_factory

pub fn index_factory<D>(
    d: u32,
    description: D,
    metric: MetricType
) -> Result<IndexImpl>where
    D: AsRef<str>,

Use the index factory to create a native instance of a Faiss index, for d-dimensional vectors. description should follow the exact guidelines as the native Faiss interface (see the Faiss wiki for examples).

Error

This function returns an error if the description contains any byte with the value \0 (since it cannot be converted to a C string), or if the internal index factory operation fails.
