NamespaceGuard

aion_server::namespace::guard

Struct NamespaceGuard

pub struct NamespaceGuard { /* private fields */ }

Expand description

Adapter-boundary guard shared by API, stream, and worker transports.

Implementations§

impl NamespaceGuard

pub const fn new(resolver: NamespaceResolver) -> Self

Build a guard from the shared namespace resolver.

pub const fn resolver(&self) -> &NamespaceResolver

Borrow the resolver backing this guard.

pub async fn scope( &self, caller: &CallerIdentity, operation: &NamespaceOperation<'_>, ) -> Result<ScopedEngine, ServerError>

Authorize and scope an operation before any engine method can be called.

Workflow-targeted operations verify durable ownership, which reads the target workflow’s recorded history through the resolver’s ownership source.

§Errors

Returns ServerError::Namespace (namespace_denied) when the caller has no grant for the requested namespace or a subscription selects another namespace. Returns a not_found wire error when the requested namespace is granted but a targeted workflow is not visible in it — foreign-owned and nonexistent workflows are deliberately indistinguishable so the guard never leaks cross-tenant existence.
