Trait List

pub trait List:
    Unpin
    + Send
    + Sync {
    // Required method
    fn next(
        &mut self,
    ) -> impl Future<Output = Result<Option<Entry>>> + MaybeSend;
}

Page trait is used by raw::Accessor to implement list operation.

Required Methods

fn next(&mut self) -> impl Future<Output = Result<Option<Entry>>> + MaybeSend

Fetch a new page of Entry

Ok(None) means all pages have been returned. Any following call to next will always get the same result.

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.
