Enum RetainedReason 

#[non_exhaustive]
pub enum RetainedReason {
    Referenced,
    GraceWindow,
    NoProviderTimestamp,
    DegradedRoots,
    UnrecognizedKey,
    CheckpointNotReleasable,

}

The reason one candidate was retained, as the sweep site knows it. Each variant is the field of RetainedCandidates it counts into, where the reason itself is described.

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.

Referenced

Counts into RetainedCandidates::referenced.

GraceWindow

Counts into RetainedCandidates::grace_window.

NoProviderTimestamp

Counts into RetainedCandidates::no_provider_timestamp.

DegradedRoots

Counts into RetainedCandidates::degraded_roots.

UnrecognizedKey

Counts into RetainedCandidates::unrecognized_key.

CheckpointNotReleasable

Counts into RetainedCandidates::checkpoint_not_releasable.

UploadSessionWindow

Counts into RetainedCandidates::upload_session_window.

UploadSessionUndecided

Counts into RetainedCandidates::upload_session_undecided.

ContentScanDeferred

Counts into RetainedCandidates::content_scan_deferred.
