Trait Checkpoint

pub trait Checkpoint:
    Send
    + Sync
    + Clone
    + Debug {
    type Error: ErrorExt + Send + Sync;

    // Required methods
    fn set_protocol(&mut self, action: ProtocolAction);
    fn last_version(&self) -> ManifestVersion;
    fn encode(&self) -> Result<Vec<u8>, Self::Error>;
    fn decode(
        bs: &[u8],

    ) -> Result<Self, Self::Error>;
}

The checkpoint by checkpoint

Required Associated Types

type Error: ErrorExt + Send + Sync

Required Methods

fn set_protocol(&mut self, action: ProtocolAction)

Set a protocol action into checkpoint

fn last_version(&self) -> ManifestVersion

The last compacted action’s version of checkpoint

fn encode(&self) -> Result<Vec<u8>, Self::Error>

Encode this checkpoint into a byte vector

fn decode( bs: &[u8], reader_version: ProtocolVersion, ) -> Result<Self, Self::Error>

Decode self from byte slice with reader protocol version, return error when reader version is not supported.

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.
