Trait PruneStorage 

pub trait PruneStorage: PrunerConfig {
    type Pruner<'a>: Default + Send
       where Self: 'a;

    // Provided method
    fn prune<'a, 'life0, 'async_trait>(
        &'a self,
        _pruner: &'life0 mut Self::Pruner<'a>,
    ) -> Pin<Box<dyn Future<Output = Result<Option<u64>>> + Send + 'async_trait>>
       where Self: Sync + 'async_trait,
             'a: 'async_trait,
             'life0: 'async_trait { ... }
}

Required Associated Types

type Pruner<'a>: Default + Send where Self: 'a

Provided Methods

fn prune<'a, 'life0, 'async_trait>( &'a self, _pruner: &'life0 mut Self::Pruner<'a>, ) -> Pin<Box<dyn Future<Output = Result<Option<u64>>> + Send + 'async_trait>>

where Self: Sync + 'async_trait, 'a: 'async_trait, 'life0: 'async_trait,

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.
