Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Register(NodeRegisterRequest)

Subscribe

SendMessage

Fields

output_id: DataId

metadata: Metadata

data: Option<DataMessage>

OutputSent

Fields

output_id: DataId

metadata: Metadata

CloseOutputs(Vec<DataId>)

OutputsDone

Signals that the node is finished sending outputs.

NextEvent

EventStreamDropped

NodeConfig

Fields

node_id: NodeId

ExtensionStore

Store an opaque value in the daemon’s dataflow-scoped extension table.

dora attaches no meaning to namespace, key or value: this is the out-of-band channel for transports that live outside the tree (see docs/extensions.md). The daemon tracks who stored a key and who has read it, so it can notify readers on removal and reclaim the entry when the dataflow ends.

Fields

namespace: String

key: String

value: Vec<u8>

ExtensionLoad

Read an opaque value back. remove: true drops it in the same round trip, so a consume-once handoff needs one request rather than two.

Fields

namespace: String

key: String

remove: bool

ExtensionDrop

Drop an opaque value. Every node that stored or loaded the key is sent [NodeEvent::ExtensionDropped] so it can release whatever the value referred to.

Fields

namespace: String

key: String

ExtensionRequest

An opaque request from a node to the extension registered under namespace on its daemon. dora never interprets either field.

Complements the extension table (ExtensionStore/ExtensionLoad/ ExtensionDrop), which brokers descriptor lifetime. This one carries a call the extension’s daemon half must service — the tensor-pool uses it for cross-machine registration and pool writes.

Fields

namespace: String

payload: Vec<u8>

Implementations

impl DaemonRequest

pub fn encode_size_hint(&self) -> usize

Bulk bytes this request will contribute to its encoding, for crate::encode_presized.

Matched exhaustively on purpose: a new payload-carrying variant that forgets to report its size would silently fall back to growing the buffer from empty, which is the cost encode_presized exists to avoid and which no test would catch.

pub fn expects_tcp_binary_reply(&self) -> bool

pub fn expects_tcp_json_reply(&self) -> bool
