Trait Cache

pub trait Cache {
    type Txn<'db>
       where Self: 'db;

    // Required method
    fn write<'db, 'async_trait>(
        &'db self,
    ) -> Pin<Box<dyn Future<Output = Self::Txn<'db>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'db: 'async_trait;
}

Required Associated Types

type Txn<'db> where Self: 'db

Required Methods

fn write<'db, 'async_trait>( &'db self, ) -> Pin<Box<dyn Future<Output = Self::Txn<'db>> + Send + 'async_trait>>

where Self: 'async_trait, 'db: '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.
