View Source Funx.Errors.EffectError exception (funx v0.1.7)

Represents a system-level failure in an effectful computation.

EffectError is raised or returned when a failure occurs during the execution of an Effect stage, such as map, bind, or ap. It is not meant for user-facing validation, but rather for internal tracing, telemetry, and diagnostics.

Fields

stage – the name of the effect stage where the error occurred (:map, :bind, :ap, etc.)
reason – the term (often an exception) that caused the failure

This error implements the Exception, String.Chars, and Funx.Summarizable behaviours.
