Enum ExternalResult 

pub enum ExternalResult {
    Resolved(Value),
    Fallback,
    Pending,
}

Result of an external function handler call.

Variants

Resolved(Value)

The handler resolved the call and returned a value. Value::Null is valid for fire-and-forget calls.

Fallback

The handler declined — use the ink fallback body if available.

Pending

The handler cannot resolve the call yet (async resolution). The VM freezes with the External frame intact. The caller must resolve via story.resolve_external(value) before continuing.
