Trait NamedGraphTraversableDataset

pub trait NamedGraphTraversableDataset: Dataset {
    type NamedGraphs<'a>: Iterator<Item = &'a Self::Resource>
       where Self: 'a;

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

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

Required Associated Types

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

Required Methods

fn named_graphs(&self) -> Self::NamedGraphs<'_>

Provided Methods

fn named_graph_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.
