AuthorityError

Enum AuthorityError 

Source
pub enum AuthorityError {
    NotDelegated,
    NotAvailable,
    NotHolder,
    NotInScope,
    ResourceNotPresent,
}
Expand description

Errors raised by entity- and resource-authority operations.

Resource* variants are raised by the Replicated Resources auth API (e.g. server.resource_take_authority::<R>()) and are semantically distinct from the entity variants — using NotInScope for “the resource isn’t currently inserted” would be a misuse.

Variants§

§

NotDelegated

Entity is not configured for delegation.

§

NotAvailable

Authority is not currently Available (e.g. another holder).

§

NotHolder

Caller does not currently hold authority.

§

NotInScope

Entity is not in the user’s scope.

§

ResourceNotPresent

(Resource API) The resource of the requested type R is not currently inserted on this server/world. Distinct from NotInScope (which is an entity-scope concept). Returned by server.resource_take_authority::<R>(), server.resource_release_authority::<R>(), and the client request_resource_authority / release_resource_authority commands when R is missing from the registry.
