Struct JsonExecutionContextFactory 

pub struct JsonExecutionContextFactory;

Default factory that wraps actor JSON in a labeled ExecutionContext.

Suitable for examples and handlers that only need ExecutionContext::label and ExecutionContext::actor_json. For application-specific identity (database sessions, permission checks, typed actors), implement ExecutionContextFactory instead.

The default label keeps short actor JSON as-is (up to 64 characters) and replaces longer payloads with a stable json:<hash> form so logs stay compact. The full actor payload remains available via actor_json.

Example

Pass to BosonBuilder::execution_context_factory at worker boot:

use std::sync::Arc;

use boson_backend_mem::MemQueueBackend;
use boson_core::JsonExecutionContextFactory;
use boson_runtime::Boson;

let _boson = Boson::builder()
    .queue_backend(Arc::new(MemQueueBackend::new()))
    .execution_context_factory(JsonExecutionContextFactory)
    .auto_registry()
    .build()?;
