Struct multi_skill::data_processing::ClosureDataset

pub struct ClosureDataset<T, F: Fn(usize) -> T> { /* fields omitted */ }

A Dataset defined in terms of a closure, which acts as a "getter".

Implementations

impl<T, F: Fn(usize) -> T> ClosureDataset<T, F>

pub fn new(length: usize, closure: F) -> Self

Trait Implementations

impl<T, F: Fn(usize) -> T> Dataset for ClosureDataset<T, F>

type Item = T

The type of objects procured by the Dataset.

fn len(&self) -> usize

The number of objects in the Dataset.

fn get(&self, index: usize) -> T

Get the index'th element, where 0 <= index < len()

fn cached(self, cache_dir: impl Into<PathBuf>) -> CachedDataset<Self> where
    Self: Sized, 

Modifies the dataset to check a cache directory before reading. If the cache entry is present, it's used instead of the underlying get(). If the cache entry is absent, it will be created after calling get().

fn iter(&self) -> Box<dyn Iterator<Item = Self::Item>>

Produces an Iterator that produces the entire Dataset in indexed order.
