Trait StorageBatchMutate

pub trait StorageBatchMutate<Type: Mappable>: StorageMutate<Type> {
    // Required methods
    fn init_storage<'a, Iter>(&mut self, set: Iter) -> Result<()>
       where Iter: 'a + Iterator<Item = (&'a Type::Key, &'a Type::Value)>,
             Type::Key: 'a,
             Type::Value: 'a;
    fn insert_batch<'a, Iter>(&mut self, set: Iter) -> Result<()>
       where Iter: 'a + Iterator<Item = (&'a Type::Key, &'a Type::Value)>,
             Type::Key: 'a,
             Type::Value: 'a;
    fn remove_batch<'a, Iter>(&mut self, set: Iter) -> Result<()>
       where Iter: 'a + Iterator<Item = &'a Type::Key>,
             Type::Key: 'a;
}

The traits allow work with the storage in batches. Some implementations can perform batch operations faster than one by one.

Required Methods

fn init_storage<'a, Iter>(&mut self, set: Iter) -> Result<()>

where Iter: 'a + Iterator<Item = (&'a Type::Key, &'a Type::Value)>, Type::Key: 'a, Type::Value: 'a,

Initialize the storage with batch insertion. This method is more performant than Self::insert_batch in some cases.

Errors

Returns an error if the storage is already initialized.

fn insert_batch<'a, Iter>(&mut self, set: Iter) -> Result<()>

where Iter: 'a + Iterator<Item = (&'a Type::Key, &'a Type::Value)>, Type::Key: 'a, Type::Value: 'a,

Inserts the key-value pair into the storage in batch.

fn remove_batch<'a, Iter>(&mut self, set: Iter) -> Result<()>

where Iter: 'a + Iterator<Item = &'a Type::Key>, Type::Key: 'a,

Removes the key-value pairs from the storage in batch.

Object Safety

This trait is not object safe.
