Implementations

source

impl<L: Log> UnreliableLog<L>

source

pub fn new(log: L) -> (Self, UnreliableHandleOld )

Returns a new UnreliableLog and a handle for controlling it.

source

pub fn from_handle(log: L, handle: UnreliableHandleOld) -> Self

Returns a new UnreliableLog sharing the given handle.
