Enum LearnRefusal 

#[non_exhaustive]
pub enum LearnRefusal {
    Reserved,
    Direct,
    Full,
}

Why a learning claim changed nothing.

It is #[non_exhaustive], so a new refusal isn’t a breaking change: a match needs a wildcard arm.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Reserved

Network 0 or 0xFFFF, which name no single network.

Direct

The network is directly attached, and learning never changes that.

Full

The network is new and the table is full.
