Struct DatabaseProviderRW 

Source 
pub struct DatabaseProviderRW<DB: Database, N: NodeTypes>(pub DatabaseProvider<<DB as Database>::TXMut, N>);
Expand description

A DatabaseProvider that holds a read-write database transaction.

Ideally this would be an alias type. However, there’s some weird compiler error (https://github.com/rust-lang/rust/issues/102211), that forces us to wrap this in a struct instead. Once that issue is solved, we can probably revert back to being an alias type.
