Trait Checkpointer 

pub trait Checkpointer<R>: Send + Sync
where
    R: Checkpoint,
{
    // Required methods
    fn save(&self, epoch: usize, record: R) -> Result<(), CheckpointerError>;
    fn delete(&self, epoch: usize) -> Result<(), CheckpointerError>;
    fn restore(&self, epoch: usize) -> Result<R, CheckpointerError>;
}

The trait for checkpointer.

Required Methods

fn save(&self, epoch: usize, record: R) -> Result<(), CheckpointerError>

Save the record.

Arguments

• epoch - The epoch.
• record - The record.

fn delete(&self, epoch: usize) -> Result<(), CheckpointerError>

Delete the checkpoint saved at the given epoch if present.

fn restore(&self, epoch: usize) -> Result<R, CheckpointerError>

Restore the record from the checkpoint saved at the given epoch.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
