[][src]Struct substrate_client::in_mem::Backend

pub struct Backend<Block, H> where
    Block: BlockT,
    H: Hasher<Out = Block::Hash>,
    H::Out: Ord
{ /* fields omitted */ }

In-memory backend. Keeps all states and blocks in memory.

Warning: Doesn't support all the features necessary for a proper database. Only use this struct for testing purposes. Do NOT use in production.
