Trait Batchable 

pub trait Batchable:
    Gettable<Key: Array, Value: CodecShared + Clone, Error = Error>
    + Updatable
    + Deletable {
    // Provided methods
    fn start_batch(&self) -> Batch<'_, Self::Key, Self::Value, Self>
       where Self: Sized + Sync,
             Self::Value: Send + Sync { ... }
    fn write_batch<'a, Iter>(
        &'a mut self,
        iter: Iter,
    ) -> impl Future<Output = Result<(), Error>> + Send + use<'a, Self, Iter>
       where Self: Send,
             Iter: Iterator<Item = (Self::Key, Option<Self::Value>)> + Send + 'a { ... }
}

A k/v store that supports making batched changes.

Provided Methods

fn start_batch(&self) -> Batch<'_, Self::Key, Self::Value, Self>

where Self: Sized + Sync, Self::Value: Send + Sync,

Returns a new empty batch of changes.

fn write_batch<'a, Iter>( &'a mut self, iter: Iter, ) -> impl Future<Output = Result<(), Error>> + Send + use<'a, Self, Iter>

where Self: Send, Iter: Iterator<Item = (Self::Key, Option<Self::Value>)> + Send + 'a,

Writes a batch of changes to the store.

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.
