Trait TraversableDataset

pub trait TraversableDataset: Dataset {
    type Quads<'a>: Iterator<Item = Quad<&'a Self::Resource>>
       where Self: 'a;

    // Required method
    fn quads(&self) -> Self::Quads<'_>;

    // Provided method
    fn quads_count(&self) -> usize { ... }
}

Dataset that can be traversed using a provided quad iterator.

Required Associated Types

type Quads<'a>: Iterator<Item = Quad<&'a Self::Resource>> where Self: 'a

Quads iterator.

Required Methods

fn quads(&self) -> Self::Quads<'_>

Returns an iterator over the quads of the dataset.

Provided Methods

fn quads_count(&self) -> usize

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
