Enum LinkRefusal 

pub enum LinkRefusal {
    Binding(SubjectBindingError),
    Export(AccessDecisionError),
    Import(AccessDecisionError),
}

Why a message did not cross, naming the end that refused it.

Variants

Binding(SubjectBindingError)

The subject could not be bound (empty, whitespace, or a pattern).

Export(AccessDecisionError)

The exporting machine’s pass holds no reaching link_export.

Import(AccessDecisionError)

The importing machine’s pass holds no reaching link_import.
