Enum AbiResult 

pub enum AbiResult {
    Ok(Value),
    Error(PluginError),
}

JSON envelope wrapping the outcome of a fallible plugin ABI call.

The low-level Wasm exports (validate, calculate_metrics, generate_passport) cannot return a Rust Result across the C ABI, so the outcome is serialised as this externally-tagged enum. On success, ok carries the method’s return value (a PluginResult for calculate_metrics, the normalised payload for generate_passport, or null for validate). On failure, error carries a structured PluginError. The host deserialises this to recover the typed result.

{ "ok": { "co2eScore": 85.4, "complianceStatus": "NOT_ASSESSED", ... } }
{ "error": { "ValidationErrors": [ { "field": "/gtin", "code": "missing", ... } ] } }

Variants
