FsFlow.Flow.tapError

Runs a synchronous side effect on failure and preserves the original error.

Remarks

Use this for error logging or cleanup actions that depend on the environment. If the binder side-effect flow itself fails, its error will overwrite the original error.

Parameters

• binder: A function that produces a side-effect flow from the error value.
• flow: The source flow.

Returns

A Flow that preserves the original error after the side effect.
