Or Operator in Validators

The Or operator function enables developers to combine validator rules using a logical OR chain. This addition allows for more nuanced validator scenarios, where a value may satisfy one of multiple conditions to be considered valid.

In Valgo, validator rules are typically chained together using an implicit AND logic. This means that for a value to be deemed valid, it must satisfy all specified conditions. The Or operator provides an alternative by allowing conditions to be linked with OR logic. In such cases, a value is considered valid if it meets at least one of the chained conditions.

The Or operator follows a simple left-to-right boolean priority, akin to the Go language’s approach to evaluating boolean expressions. Valgo does not have an equivalent to parentheses in API functions, in order to keep the syntax simple and readable. We believe that complex boolean logic becomes harder to read with a Fluent API interface, so for those cases, it is preferred to use imperative Go programming language constructs.
