PrimerValidationStatus is an enum that represents the different validation statuses in the Primer SDK. It helps to communicate the state of validation for a particular process, providing clear categorization of validation states.

enum PrimerValidationStatus

Enum case representing the ongoing validation state. This indicates that the validation process is currently in progress.

Enum case representing a successful validation state. This indicates that the validation process has completed successfully and the data is valid.

Enum case representing an unsuccessful validation state due to validation errors. This indicates that the validation process has completed but has found one or more errors in the data.

Associated Value

An array of `PrimerValidationError` representing the specific validation errors found.

Enum case representing an error state due to an unexpected issue. This indicates that an unexpected error has occurred during the validation process.

Associated Value

A `PrimerError` representing the unexpected error that occurred.

Whenever start or submit methods are called, stepDelegate will trigger the next step in case the call to the mentioned method was successful.
