validate

Validates a value against a set of validation rules.

This function applies all the provided validation rules to the given value and collects any validation error messages. If all rules pass, it returns ValidationResult.Valid. If any rules fail, it returns a ValidationResult.Invalid containing all the error messages.

Usage:

val rules = rules<String> {
    notBlank { "Required" }
    minLength(3) { "Too short" }
}
val result = validate("ab", rules)
// ValidationResult.Invalid.messages will contain ["Too short"]
