Implementations

impl<I> InMemDataset<I>

pub fn new(items: Vec<I>) -> InMemDataset<I>

Creates a new in memory dataset from the given items.

impl<I> InMemDataset<I>

where I: Clone + DeserializeOwned,

pub fn from_dataset(dataset: &impl Dataset<I>) -> InMemDataset<I>

Create from a dataset. All items are loaded in memory.

pub fn from_json_rows<P>(path: P) -> Result<InMemDataset<I>, Error>

where P: AsRef<Path>,

Create from a json rows file (one json per line).
