Struct CheckpointView 

pub struct CheckpointView {
    pub workspace_id: String,
    pub epoch: Option<String>,
    pub patch_set: Option<PatchSet>,
    pub patch_set_oid: Option<String>,
    pub description: Option<String>,
    pub annotations: BTreeMap<String, BTreeMap<String, Value>>,
    pub is_destroyed: bool,
}

Subset of MaterializedView that is checkpointed.

We serialize only the essential state, not the full MaterializedView struct, to keep checkpoints forward-compatible.

Fields

workspace_id: String

The workspace this view belongs to.

epoch: Option<String>

Current epoch (from latest Create or Merge).

patch_set: Option<PatchSet>

Current patch set (serialized).

patch_set_oid: Option<String>

Patch set blob OID.

description: Option<String>

Description.

annotations: BTreeMap<String, BTreeMap<String, Value>>

Annotations (excluding checkpoint annotations themselves).

is_destroyed: bool

Whether workspace is destroyed.

Implementations

impl CheckpointView

pub fn from_view(view: &MaterializedView) -> Self

Convert a MaterializedView to checkpoint-serializable form.

pub fn to_view( &self, op_count: usize, ) -> Result<MaterializedView, CheckpointError>

Restore a MaterializedView from checkpoint data.

Errors

Returns CheckpointError::InvalidData if OIDs cannot be parsed.

Trait Implementations

impl Clone for CheckpointView

fn clone(&self) -> CheckpointView

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CheckpointView

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CheckpointView

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for CheckpointView

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
