Struct WalWrapper

pub struct WalWrapper<T, W> { /* private fields */ }

A convenient wrapper struct that implement WAL with a wrapper where the wrapper needs to implement WrapWal instead of Wal, where all methods delegate to wrapped by default.

Implementations

where T: WrapWal<W::Wal> + Clone, W: WalManager,

pub fn new(wrapper: T, wrapped: W) -> Self
