Module offload 

Offload trait for background task execution.

This module provides the Offload trait which abstracts over different implementations for spawning background tasks.

Lifetime Parameter

The Offload<'a> trait is parameterized by a lifetime to support both:

• 'static futures (for real background execution with OffloadManager)
• Non-'static futures (for middleware integration with DisabledOffload)

This design allows CacheFuture to work with borrowed upstreams (like reqwest middleware’s Next<'_>) when background revalidation is not needed.

Structs

DisabledOffload

A disabled offload implementation that discards all spawned tasks.

Traits
