Trait StorageIterator 

pub trait StorageIterator {
    // Required method
    fn next<'life0, 'async_trait>(
        &'life0 mut self,
    ) -> Pin<Box<dyn Future<Output = StorageResult<Option<Record>>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait;
}

Iterator over storage records.

Required Methods

fn next<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = StorageResult<Option<Record>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Returns the next record from this iterator.

Returns Ok(None) when the iterator is exhausted.

Dyn Compatibility

This trait is dyn compatible.

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