boson-backend-mem

In-memory QueueBackend adapter for tests, CI, and local development.

Role

Implements QueueBackend using portable DTOs from boson-core — no network I/O or host-specific persistence.

Used by:

• boson-testkit default BootstrapSession
• Inline integration tests and boson-e2e CI slice
• boson-bench backend=mem campaigns

Compose

use std::sync::Arc;

use boson::{Boson, MemQueueBackend};

let backend = Arc::new(MemQueueBackend::new());
let boson = Boson::builder()
    .queue_backend(backend)
    .execution_context_factory(your_factory)
    .build()?;

Bootstrap

use boson_backend_mem::install_default_mem_backend;
use boson_core::default_backend_from_global;

let _backend = install_default_mem_backend();
let resolved = default_backend_from_global()?;

Enable via boson

Available via the boson crate feature mem (forwards this adapter).
