Struct StepError 

pub struct StepError(/* private fields */);

The error channel for a step’s operation closure.

The durable layer is Layer-0 infrastructure and must not depend on any consumer’s error enum (INV-1), so a closure reports failure through this opaque wrapper. Construct it from any boxable error (or a message) with StepError::new; the wrapped error stays reachable through DurableError::StepFailed’s source.

Examples

use zeph_durable::StepError;

// From a message:
let _ = StepError::new("provider returned 503");
// From a concrete error:
let io = std::io::Error::other("disk full");
let _ = StepError::new(io);

Implementations
