failure.unknown_mapping
Mapping names a condition the operation does not have.
Area 4, Failures; not declinable; the next step is usually the agent's.
A construction's arms are the rules of its type:
type Quantity = Int { min: 1 max: 1000}type QuantityTooLarge = Failure { kind: FailureKind.invalid_value}function doubled(quantity: Quantity) fails QuantityTooLarge -> Quantity { var result: Quantity = attempt Quantity(quantity * 2) { maximum: QuantityTooLarge } return result}
error: `Quantity(...)` has no `maximum:` condition to map --> main.jadpo:12:9 |12 | maximum: QuantityTooLarge | ^^^^^^^ not a condition here reason: A construction's arms are the rules of its type and the types it builds on; `Quantity(...)`'s are `min` and `max`, and `invalid:` covers any without an arm of its own. next: Remove `maximum: ...`, or map one of `min` and `max` instead (agent) rule: failure.unknown_mapping help: https://jadpo.dev/docs/errors/failure.unknown_mappingcheck failed: 1 error, 1 file
