rskit-chain

Typed sequential chain execution for rskit.

rskit-chain builds statically typed async chains where each step receives the previous step's output and returns the next step's input. Execution short-circuits on the first AppError, checks cancellation between steps, and runs cleanup handlers for completed steps when later work fails or is cancelled.

Features

• Fluent ChainBuilder API for heterogeneous step composition.
• Step::from_fn adapters for async functions.
• Progress callbacks with step status events.
• Cleanup hooks for compensating completed steps.
• CancellationToken support for cooperative cancellation.
