Enum WalOp 

pub enum WalOp {
    CreateCollection {
        collection_id: CollectionId,
        name: String,
        descriptor: Vec<u8>,
    },
    DropCollection {
        collection_id: CollectionId,
    },
    Upsert {
        collection_id: CollectionId,
        external_id: String,
        vector: Vec<u8>,
        payload: Vec<u8>,
    },
    Delete {
        collection_id: CollectionId,
        external_id: String,
    },
    Checkpoint {
        last_checkpointed_lsn: Lsn,
        manifest_version: u64,
    },
}

A single logical mutation recorded in the WAL.

The vector and payload are stored as opaque bytes: the engine validates and interprets them (the descriptor fixes the vector dtype/dim; payloads are validated JSON), keeping the log a dumb, stable durability primitive.

Variants

CreateCollection

Create a collection with the given id, name, and postcard-encoded descriptor.

Fields

collection_id: CollectionId

Identifier assigned to the new collection.

name: String

Human-readable collection name, unique within the store.

descriptor: Vec<u8>

Postcard-encoded collection descriptor (schema, dim, dtype, metric).

DropCollection

Drop a collection and all of its data.

Fields

collection_id: CollectionId

Identifier of the collection to drop.

Upsert

Insert or replace a point.

Fields

collection_id: CollectionId

Owning collection.

external_id: String

Caller-supplied external identifier.

vector: Vec<u8>

Raw little-endian vector element bytes (dtype per the descriptor).

payload: Vec<u8>

Opaque, pre-validated payload bytes (UTF-8 JSON in Phase 1).

Delete

Delete a point by external id.

Fields

collection_id: CollectionId

Owning collection.

external_id: String

External identifier to delete.

Checkpoint

Record that state up to last_checkpointed_lsn is durable in segments referenced by manifest version manifest_version.

Fields

last_checkpointed_lsn: Lsn

Highest LSN now captured in sealed segments.

manifest_version: u64

Manifest version that references those segments.

Trait Implementations

impl Clone for WalOp

fn clone(&self) -> WalOp

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WalOp

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for WalOp

fn deserialize<__D>( __deserializer: __D, ) -> Result<WalOp, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for WalOp

impl PartialEq for WalOp

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
