Namespace

Cratis.Arc.Validation

Assembly

Remarks

Whether a value is well formed is a property of its type, not of the operation carrying it — a ConceptValidator<T> for an identifier means the same thing on a command as it does on a query argument. This is the single traversal both pipelines use, so a validator behaves identically wherever the value it guards appears.

Methods

Validate(ModelGraphValidationRequest, CancellationToken)

Validates an object graph, running validators for the root and for everything reachable from it.

Task<IEnumerable<ValidationResult>> Validate(ModelGraphValidationRequest request, CancellationToken cancellationToken = default)

Parameters

request ModelGraphValidationRequest

The ModelGraphValidationRequest describing what to validate.

cancellationToken CancellationToken

Optional CancellationToken for cancelling the validation.

Returns

Task<IEnumerable<ValidationResult>>

The ValidationResult collection describing every failure found, empty when valid.
