Enum mail_headers::error::BuildInValidationError

pub enum BuildInValidationError {

}

The build-in error variants (error kinds) which can be returned when running a header map validator.

Variants

MaxOneInconsistency

This error is returned by use_contextual_validators if there is a "max one" inconsistency.

I.e. if multiple implementations of the same header are used in the same map but the implementations do not agree on wether or not the header can appear at most one time in a header section.
