Struct DroppedCollection 

pub struct DroppedCollection {
    pub tenant_id: u32,
    pub name: String,
    pub owner: String,
    pub engine_type: String,
    pub deactivated_at_ns: u64,
    pub retention_expires_at_ns: u64,
}

A soft-deleted collection awaiting either UNDROP or retention-driven hard deletion.

Fields

tenant_id: u32

Tenant that owns this collection.

name: String

Collection name (unique per tenant while soft-deleted).

owner: String

Preserved owner at the time of DROP — the user who can UNDROP without superuser/tenant_admin elevation. Empty string if the owner row could not be resolved at the time of the catalog read.

engine_type: String

Engine / collection-type slug resolved from StoredCollection.collection_type.as_str(). One of "document", "strict", "columnar", "timeseries", "columnar:spatial", "kv". Drives operator dashboards that need to group pending-purge rows by engine.

deactivated_at_ns: u64

Wall-clock nanoseconds when DROP COLLECTION was committed (from stored.modification_hlc.wall_ns).

retention_expires_at_ns: u64

Wall-clock nanoseconds at which the retention window elapses and the sweeper will hard-delete this row. Derived from deactivated_at_ns + retention_window.

Implementations

impl DroppedCollection

pub fn is_expired(&self, now_ns: u64) -> bool

Whether the retention window has already elapsed as of now_ns. Rows with is_expired(now_ns) == true are candidates for the next sweeper pass; they may appear in the list briefly before the sweeper runs.

Trait Implementations

impl Clone for DroppedCollection

fn clone(&self) -> DroppedCollection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DroppedCollection

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DroppedCollection

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for DroppedCollection

fn eq(&self, other: &DroppedCollection) -> 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 DroppedCollection

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
