Enum Role 

#[non_exhaustive]
pub enum Role {
    Publisher,
    Subscriber,
}

The session direction a client advertises in its SETUP (moq-lite-05+). The single direction a client intends to use the session for.

A client advertises this in its SETUP so the server can reject a token that lacks the matching scope during the handshake, instead of accepting a connection that then silently carries no media (a subscribe-only token used to publish, or vice versa). It only ever narrows what the server grants, so it is not a security boundary: the server still enforces the token’s scope regardless.

A session is bidirectional by default, which the wire says by omitting the parameter. Option<Role> mirrors that: None is the default, and it’s also what a client that predates the parameter decodes to.

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.

Publisher

The client will publish tracks (ingest); the server must consume.

Subscriber

The client will subscribe to tracks (egress); the server must publish.
