Struct CheckpointAnchor 

pub struct CheckpointAnchor {
    pub predecessor: Prefix,
    pub position: Prefix,
    pub schema: Digest,
    pub state_digest: Digest,
    pub state_bytes: u64,
    pub chunk_bytes: u32,
}

Exact pinned checkpoint and the predecessor of required retained operations.

Fields

predecessor: Prefix

Hash anchor before the first retained operation, possibly before state.

position: Prefix

Original confirmed operation prefix represented by canonical state.

schema: Digest

Exact canonical state schema digest.

state_digest: Digest

Integrity digest over all checkpoint state bytes.

state_bytes: u64

Bounded logical state size, independently checked by the storage adapter.

chunk_bytes: u32

Maximum bytes in each immutable source chunk.

Implementations

impl CheckpointAnchor

pub fn validate(self, committed: Prefix) -> Result<(), RecoveryError>
