Struct AccessControl 

pub struct AccessControl { /* private fields */ }

Per-rider access control: which stops the rider is allowed to visit.

When absent from a rider entity, the rider has unrestricted access. When present, can_access returns true either when the queried stop is in allowed_stops or when the set is empty — an empty set means “no restriction” (matches AccessControl::default() and the principle-of-least- surprise that an empty allowlist shouldn’t silently block all access). To explicitly block all stops, use a sentinel set or a dedicated no-access wrapper. (#289)

Implementations

impl AccessControl

pub const fn new(allowed_stops: HashSet<EntityId>) -> Self

Create a new access control with the given set of allowed stops. Pass an empty set for “no restriction” (unrestricted access).

pub fn can_access(&self, stop: EntityId) -> bool

Check if the rider can access the given stop.

An empty allowed_stops set is treated as “no restriction” — can_access returns true for any stop. A non-empty set is an allowlist; stop must be a member.

pub const fn allowed_stops(&self) -> &HashSet<EntityId>

The set of allowed stop entity IDs. Empty means unrestricted.
