Struct StreamMetadata 

pub struct StreamMetadata {
    pub provenance: Vec<String>,
    pub plexus_hash: String,
    pub timestamp: i64,
}

Metadata applied by the caller when wrapping activation responses

This metadata is added at each layer of the call stack, enabling provenance tracking and cache invalidation.

Fields

provenance: Vec<String>

Call path through the system (e.g., [“substrate”, “health”])

plexus_hash: String

Hash of Plexus RPC server configuration for cache invalidation Changes when activations are added/removed/updated

timestamp: i64

Unix timestamp (seconds) when the event was wrapped

Implementations

impl StreamMetadata

pub fn new(provenance: Vec<String>, plexus_hash: String) -> StreamMetadata

Create new metadata with current timestamp

Trait Implementations

impl Clone for StreamMetadata

fn clone(&self) -> StreamMetadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StreamMetadata

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for StreamMetadata

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for StreamMetadata

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.

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.
