Struct StagingSpec 

pub struct StagingSpec {
    pub timeout: Option<String>,
    pub storage_class_name: Option<String>,
    pub access_modes: Vec<PvcAccessMode>,
}

SnapshotPolicy.spec.staging — knobs for the CSI capture (copyMethod: Snapshot/Clone) that runs before the mover. A sub-object so future staging fields slot in without API breakage.

Fields

timeout: Option<String>

How long each staging phase may take before the backup is failed (Go-style duration like 10m or 1h; default 10m): first the staged VolumeSnapshot becoming readyToUse (measured from its creation), then — on an Immediate-binding StorageClass — the staged PVC binding (a fresh budget measured from the PVC’s creation, covering the CSI restore/clone). A transient CSI/snapshot-controller error during either wait is retried, never fatal on its own — only this deadline fails staging. A zero duration (0/0s) waits indefinitely. Raise this for backends whose snapshots or clones take long (e.g. cloud snapshots of large volumes, CephFS full clones of small-file-heavy volumes).

storage_class_name: Option<String>

StorageClass for the staged PVC — the temporary PVC restored from the CSI VolumeSnapshot (copyMethod: Snapshot) or cloned from the source (copyMethod: Clone). Absent ⇒ the staged PVC copies the source PVC’s class. Must belong to the same CSI driver as the source (staging fails fast on a mismatch). Flagship use: a rook-ceph CephFS class with backingSnapshot: "true", which mounts the snapshot shallowly (metadata-only, near-instant, read-only) instead of running a full subvolume clone that can take many minutes on small-file-heavy volumes.

access_modes: Vec<PvcAccessMode>

Access modes for the staged PVC. Empty ⇒ copy the source PVC’s modes. [ReadOnlyMany] pairs with snapshot-backed read-only classes (e.g. CephFS backingSnapshot); the mover mounts the staged PVC read-only to match, and rejects it at admission if a source sets readOnly: false (a read-only stage cannot be mounted read-write).

Trait Implementations

impl Clone for StagingSpec

fn clone(&self) -> StagingSpec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StagingSpec

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

Formats the value using the given formatter.

impl Default for StagingSpec

fn default() -> StagingSpec

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for StagingSpec

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for StagingSpec

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 StagingSpec

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
