Enum PolicyDeletePolicy 

pub enum PolicyDeletePolicy {
    Retain,
    Delete,
}

What the deletion of a SnapshotPolicy does to the Snapshot CRs carrying its config label (the recipe’s produced/adopted rows — NOT its kopia snapshot history in the abstract, which is exactly what Retain preserves). Default Retain: the CRs are removed but every kopia snapshot survives (rediscoverable/adoptable by a future SnapshotPolicy, including this one re-created). Delete opts into the cascade: each CR’s own deletionPolicy applies, as EXTERNAL deletions subject to the per-repository mass-deletion breaker (deletionProtection.threshold).

Deliberately 2-variant (not reusing DeletionPolicy), mirroring ScheduleDeletePolicy: an Orphan in cascade position would differ from Retain only in per-CR event/metric bookkeeping — an invalid state made unrepresentable. The guard’s Retain is exactly DeletionPolicy::Retain’s semantics (CR removed, kopia snapshot stays, catalog rediscovers it), deliberately NOT the Orphan event storm (no per-CR “orphaned” event/metric for every one of a deleted policy’s Snapshots). Not ScheduleDeletePolicy itself: that type’s doc contract is schedule-specific (its Delete arm talks about a schedule being gone/replaced), and a SnapshotPolicy deletion is a distinct trigger with its own semantics worth documenting on its own type.

Variants

Retain

Keep the kopia snapshots: a Snapshot whose effective deletionPolicy is Delete is downgraded to retain when its owning SnapshotPolicy is gone (the fail-safe default).

Delete

Cascade: each Snapshot’s own deletionPolicy applies even though the owning SnapshotPolicy is gone (subject to the mass-deletion breaker).

Trait Implementations

impl Clone for PolicyDeletePolicy

fn clone(&self) -> PolicyDeletePolicy

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PolicyDeletePolicy

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for PolicyDeletePolicy

fn default() -> PolicyDeletePolicy

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for PolicyDeletePolicy

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for PolicyDeletePolicy

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for PolicyDeletePolicy

fn eq(&self, other: &PolicyDeletePolicy) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for PolicyDeletePolicy

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for PolicyDeletePolicy

impl Eq for PolicyDeletePolicy
