Enum NearestTimestamp 

#[non_exhaustive]
pub enum NearestTimestamp {
    Earliest(Timestamp),
    Latest(Timestamp),
    Unknown,
}

The nearest retained timestamp on the side of the search bound that an out-of-range search failed against. Engines surface this to users so the error message can point at a valid timestamp.

Earliest and Latest carry the boundary commit’s timestamp. Unknown means no boundary timestamp was available, e.g. empty log or a failure reading the boundary commit’s In-Commit Timestamp at the error site.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Earliest(Timestamp)

The earliest retained commit’s timestamp. Returned for a GreatestLower search whose input fell below the retained range.

Latest(Timestamp)

The latest retained commit’s timestamp. Returned for a LeastUpper search whose input fell above the retained range.

Unknown

No boundary timestamp could be determined.
