Struct DistributedContext 

pub struct DistributedContext {
    pub session_id: String,
    pub data: HashMap<String, Value>,
    pub metadata: ContextMetadata,
}

A distributed context that can be serialized and shared across services

Fields

session_id: String

Unique session identifier

data: HashMap<String, Value>

Context data

metadata: ContextMetadata

Metadata for tracking

Implementations

impl DistributedContext

pub fn new(session_id: impl Into<String>) -> Self

Create a new distributed context

Example

use rust_logic_graph::distributed::DistributedContext;

let context = DistributedContext::new("session-123");
assert_eq!(context.session_id, "session-123");

pub fn set(&mut self, key: impl Into<String>, value: Value)

Set a value in the context

pub fn get(&self, key: &str) -> Option<&Value>

Get a value from the context

pub fn remove(&mut self, key: &str) -> Option<Value>

Remove a value from the context

pub fn serialize(&self) -> Result<Vec<u8>>

Serialize context to bytes for transmission

Uses MessagePack for efficient binary serialization

pub fn deserialize(bytes: &[u8]) -> Result<Self>

Deserialize context from bytes

pub fn to_json(&self) -> Result<String>

Serialize to JSON (for debugging/human-readable)

pub fn from_json(json: &str) -> Result<Self>

Deserialize from JSON

pub fn snapshot(&self) -> ContextSnapshot

Create a snapshot of current context state

pub fn merge(&mut self, other: &DistributedContext)

Merge another context into this one

Performs a simple merge where newer values win

pub fn add_tag(&mut self, tag: impl Into<String>)

Add a tag to the context

pub fn set_modified_by(&mut self, service: impl Into<String>)

Set the service that modified this context
