Trait Checkpointable

pub trait Checkpointable:
    Send
    + Sync
    + Sized {
    type State: RemoteMessage;

    // Required methods
    fn save<'life0, 'async_trait>(
        &'life0 self,
    ) -> Pin<Box<dyn Future<Output = Result<Self::State, CheckpointError>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait;
    fn load<'async_trait>(
        state: Self::State,
    ) -> Pin<Box<dyn Future<Output = Result<Self, CheckpointError>> + Send + 'async_trait>>
       where Self: 'async_trait;
}

[Checkpoint] is used to save the state of an instance so that it can be restored later.

Required Associated Types

type State: RemoteMessage

The type of the state that is saved. The state can be serialized and deserialized from persistent storage.

Required Methods

fn save<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Self::State, CheckpointError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Saves the current state.

fn load<'async_trait>( state: Self::State, ) -> Pin<Box<dyn Future<Output = Result<Self, CheckpointError>> + Send + 'async_trait>>

where Self: 'async_trait,

Loads the a state to restore the instance.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
