Trait Checkpoint 

pub trait Checkpoint {
    // Required methods
    fn checkpoint(&self) -> Result<Vec<u8>, Error>;
    fn restore(&mut self, data: &[u8]) -> Result<(), Error>;
}

Trait for types that can be check-pointed and restored.

This is to be used for any additional state within circuit operators that’s not stored within a batch (which are already stored in files).

Required Methods

fn checkpoint(&self) -> Result<Vec<u8>, Error>

fn restore(&mut self, data: &[u8]) -> Result<(), Error>
