Scope stack lifecycle and mark-event entry points.

## Structs

* [CreateScopeHandleParams](/reference/api/rust-library-reference/nemo-relay/api/scope/struct-createscopehandleparams): Builder parameters for [`NemoRelayContextState::create_scope_handle`](/reference/api/rust-library-reference/nemo-relay/api/runtime/state/struct-nemorelaycontextstate).
* [EmitMarkEventParams](/reference/api/rust-library-reference/nemo-relay/api/scope/struct-emitmarkeventparams): Builder parameters for [`event`](/reference/api/rust-library-reference/nemo-relay/api/scope/fn-event).
* [EndScopeHandleParams](/reference/api/rust-library-reference/nemo-relay/api/scope/struct-endscopehandleparams): Builder parameters for [`NemoRelayContextState::build_scope_end_event`](/reference/api/rust-library-reference/nemo-relay/api/runtime/state/struct-nemorelaycontextstate).
* [PopScopeParams](/reference/api/rust-library-reference/nemo-relay/api/scope/struct-popscopeparams): Builder parameters for [`pop_scope`](/reference/api/rust-library-reference/nemo-relay/api/scope/fn-pop-scope).
* [PushScopeParams](/reference/api/rust-library-reference/nemo-relay/api/scope/struct-pushscopeparams): Builder parameters for [`push_scope`](/reference/api/rust-library-reference/nemo-relay/api/scope/fn-push-scope).
* [ScopeAttributes](/reference/api/rust-library-reference/nemo-relay/api/scope/struct-scopeattributes): Bitflags that modify scope behavior and observability.
* [ScopeHandle](/reference/api/rust-library-reference/nemo-relay/api/scope/struct-scopehandle): Runtime-owned handle identifying an active or completed scope.

## Enums

* [HandleAttributes](/reference/api/rust-library-reference/nemo-relay/api/scope/enum-handleattributes): Attribute bitflags attached to a concrete handle kind.
* [ScopeType](/reference/api/rust-library-reference/nemo-relay/api/scope/enum-scopetype): Semantic category attached to a scope lifecycle span.

## Functions

* [event](/reference/api/rust-library-reference/nemo-relay/api/scope/fn-event): Emit a standalone mark event under the current or provided scope.
* [get\_handle](/reference/api/rust-library-reference/nemo-relay/api/scope/fn-get-handle): Return the current scope at the top of the active stack.
* [pop\_scope](/reference/api/rust-library-reference/nemo-relay/api/scope/fn-pop-scope): Pop the current scope from the active scope stack.
* [push\_scope](/reference/api/rust-library-reference/nemo-relay/api/scope/fn-push-scope): Push a new scope onto the active scope stack.
