MonadicSharp.RecoverySelf-healing pipelines for .NET

Intercept specific failures, attempt recovery, and merge back to the success track — without breaking Railway-Oriented Programming flow.

The Three Lanes

GitHub

🔄

RescueAsync

One-shot recovery. When a specific error occurs, attempt a single corrective action and merge back to the green track. If recovery fails, stay on the red track.

RescueAsync docs

🔁

StartFixBranchAsync

Multi-attempt recovery with configurable delay. Try up to N times before giving up — each attempt is logged, delayable, and can target specific error predicates.

The Three Lanes

Green (success), Amber (recovery), Red (failure). Recovery.Amber is a first-class lane — not an exception handler bolted on top.

Recovery Telemetry

Implement IRecoveryTelemetry to receive structured events for every recovery attempt — start, success, failure, and exhaustion. Integrates with OpenTelemetry.

🎯

Error Predicates

Target only the errors that should trigger recovery. Predicates compose — match by type, code, severity, or any custom condition. Other errors pass through unchanged.

🔗

Composable

Recovery operators chain naturally with MonadicSharp Bind/Map. No wrapping, no unwrapping — the amber track is transparent to the rest of your pipeline.
