Struct InMemDataset

pub struct InMemDataset<I> { /* private fields */ }
Expand description

Dataset where all items are stored in ram.

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).

Supported field types

pub fn from_csv<P>( path: P, builder: &ReaderBuilder, ) -> Result<InMemDataset<I>, Error>
where P: AsRef<Path>,

Create from a csv file.

The provided csv::ReaderBuilder can be configured to fit your csv format.

The supported field types are: String, integer, float, and bool.
