Trait Adapter 

pub trait Adapter: Observer + Emitter {
    // Provided method
    fn ensure_schema<'life0, 'life1, 'async_trait>(
        &'life0 self,
        _schema: &'life1 Schema,
    ) -> Pin<Box<dyn Future<Output = Result<ProvisionReport>> + Send + 'async_trait>>
       where Self: Sync + 'async_trait,
             'life0: 'async_trait,
             'life1: 'async_trait { ... }
}

full adapter contract for read+write backends; may also provision schema.

Provided Methods

fn ensure_schema<'life0, 'life1, 'async_trait>( &'life0 self, _schema: &'life1 Schema, ) -> Pin<Box<dyn Future<Output = Result<ProvisionReport>> + Send + 'async_trait>>

where Self: Sync + 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Dyn Compatibility

This trait is dyn compatible.

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