Trait ResourceTraversableDataset

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

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

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

Required Associated Types

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

Required Methods

fn resources(&self) -> Self::Resources<'_>

Provided Methods

fn resource_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.
