Trait Indexable 

pub trait Indexable<T>: Send + Sync {
    // Required methods
    fn get(&self, i: usize) -> &[T];
    fn len(&self) -> usize;

    // Provided method
    fn is_empty(&self) -> bool { ... }
}

A trait representing a dataset that can be accessed into vector chunks.

This abstracts over the actual memory layout of the dataset, allowing the knn function to seamlessly map over a sliced array (&[T], dim), vectors of vectors Vec<Vec<T>>, or arrays of references Vec<&[T]>.

Required Methods

fn get(&self, i: usize) -> &[T]

fn len(&self) -> usize

Provided Methods

fn is_empty(&self) -> bool

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
