Struct RootVerification 

pub struct RootVerification {
    pub at_seq: u64,
    pub record: RecordStatus,
    pub recomputation: Recomputation,
    pub recomputed: Option<StateRoot>,
}

The result of checking one persisted root.

Two facts, reported separately AND ON PURPOSE:

root_record:   valid
recomputation: unavailable
reason:        HISTORY_PRUNED

Flattening that into PASS would claim a check that never ran. Flattening it into FAIL would report tampering that never happened. A pruned database is not a corrupt one, and an operator who cannot tell the two apart will either ignore real alarms or panic at routine ones.

Fields

at_seq: u64

record: RecordStatus

recomputation: Recomputation

recomputed: Option<StateRoot>

What the recomputation produced, when one happened.

Implementations

impl RootVerification

pub fn is_verified(&self) -> bool

True only when a recomputation actually ran and agreed. Deliberately NOT !is_failure(): “unavailable” is neither.

pub fn is_mismatch(&self) -> bool

True only on a positive disagreement — a recomputation ran and did not match. This is the one that means something is wrong.

pub fn exit_code(&self) -> i32

The process exit code this outcome deserves. Three states, three codes, because a caller that scripts against this must be able to tell “checked and good” from “could not check”.

Trait Implementations
