Metadata required by a storage instance to read a storage collection

Fields

persist_location: PersistLocation

The persist location where the shards are located.

remap_shard: Option<ShardId>

The persist shard id of the remap collection used to reclock this collection.

data_shard: ShardId

The persist shard containing the contents of this storage collection.

status_shard: Option<ShardId>

The persist shard containing the status updates for this storage collection.

relation_desc: RelationDesc

The RelationDesc that describes the contents of the data_shard.

txns_shard: Option<ShardId>

The shard id of the txn-wal shard, if self.data_shard is managed by the txn-wal system, or None if it’s not.

Trait Implementations

impl AlterCompatible for CollectionMetadata

fn alter_compatible(&self, id: GlobalId, other: &Self) -> Result<(), AlterError>

impl Arbitrary for CollectionMetadata

type Parameters = (<PersistLocation as Arbitrary>::Parameters, <Option<ShardId> as Arbitrary>::Parameters, <ShardId as Arbitrary>::Parameters, <Option<ShardId> as Arbitrary>::Parameters, <RelationDesc as Arbitrary>::Parameters, <Option<ShardId> as Arbitrary>::Parameters)

The type of parameters that arbitrary_with accepts for configuration of the generated Strategy. Parameters must implement Default.

type Strategy = Map<(<PersistLocation as Arbitrary>::Strategy, <Option<ShardId> as Arbitrary>::Strategy, <ShardId as Arbitrary>::Strategy, <Option<ShardId> as Arbitrary>::Strategy, <RelationDesc as Arbitrary>::Strategy, <Option<ShardId> as Arbitrary>::Strategy), fn(_: (PersistLocation, Option<ShardId>, ShardId, Option<ShardId>, RelationDesc, Option<ShardId>)) -> CollectionMetadata>

The type of Strategy used to generate values of type Self.

fn arbitrary_with(_top: Self::Parameters) -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self). The strategy is passed the arguments given in args.

fn arbitrary() -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self).

impl Clone for CollectionMetadata

fn clone(&self) -> CollectionMetadata

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CollectionMetadata

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CollectionMetadata

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for CollectionMetadata

fn eq(&self, other: &CollectionMetadata) -> 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 ProtoMapEntry<GlobalId, CollectionMetadata> for ProtoSourceImport

fn from_rust<'a>(entry: (&'a GlobalId, &'a CollectionMetadata)) -> Self

fn into_rust(self) -> Result<(GlobalId, CollectionMetadata), TryFromProtoError>

impl RustType<ProtoCollectionMetadata> for CollectionMetadata

fn into_proto(&self) -> ProtoCollectionMetadata

Convert a Self into a Proto value.

fn from_proto(value: ProtoCollectionMetadata) -> Result<Self, TryFromProtoError>

Consume and convert a Proto back into a Self value.

fn into_proto_owned(self) -> Proto

A zero clone version of Self::into_proto that types can optionally implement, otherwise, the default implementation delegates to Self::into_proto.

impl Serialize for CollectionMetadata

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for CollectionMetadata

impl StructuralPartialEq for CollectionMetadata
