Struct ConsistentDbView

Source 
pub struct ConsistentDbView<Factory> { /* private fields */ }
Expand description

A consistent view over state in the database.

View gets initialized with the latest or provided tip. Upon every attempt to create a database provider, the view will perform a consistency check of current tip against the initial one.

§Usage

The view should only be used outside of staged-sync. Otherwise, any attempt to create a provider will result in ConsistentViewError::Syncing.

When using the view, the consumer should either

  1. have a failover for when the state changes and handle ConsistentViewError::Inconsistent appropriately.
  2. be sure that the state does not change.
