Struct InstalledCheckpoint 

pub struct InstalledCheckpoint {
    pub ordinal: u64,
    pub checkpoint_id: String,
    pub previous_checkpoint_id: Option<String>,
    pub covered_head: String,
    pub through_step_seq: u64,
    pub state_digest: String,
    pub checkpoint_bytes: Vec<u8>,
    pub acknowledged: bool,
}

An installed checkpoint. Flattens node’s InstalledCheckpoint extends CheckpointCandidate.

Fields

ordinal: u64

Monotonic install ordinal. previous_checkpoint_id == None installs ordinal 0.

checkpoint_id: String

previous_checkpoint_id: Option<String>

covered_head: String

The record digest at through_step_seq — verified at install, not required to still be head.

through_step_seq: u64

state_digest: String

checkpoint_bytes: Vec<u8>

acknowledged: bool

Whether KernelJournal::ack_checkpoint has run. Prefix reclamation is gated on this: a checkpoint that is installed but not acknowledged is recoverable-from but not prune-authorising (spec §12.3 rules 5–6).
