# Function nemo_relay_scope_stack_create

> Create a new isolated scope stack with its own root scope.

Generated from `cargo doc --no-deps -p nemo-relay -p nemo-relay-adaptive -p nemo-relay-pii-redaction -p nemo-relay-ffi -p nemo-relay-types -p nemo-relay-plugin -p nemo-relay-worker-proto -p nemo-relay-worker`.

<pre />

Create a new isolated scope stack with its own root scope.

Each scope stack is independent: scopes pushed on one do not appear on another. Use `nemo_relay_scope_stack_set_thread` to bind a stack to the current thread before making other NeMo Relay API calls.

## Parameters

* `out`: On success, receives a heap-allocated `FfiScopeStack` that must be freed with `nemo_relay_scope_stack_free`.

## Returns

* Returns [`NemoRelayStatus::Ok`](/reference/api/rust-library-reference/nemo-relay-ffi/error/enum-nemorelaystatus) on success and writes the new scope stack to `out`.
* Returns [`NemoRelayStatus::NullPointer`](/reference/api/rust-library-reference/nemo-relay-ffi/error/enum-nemorelaystatus) when `out` is null.

## Safety

`out` must be a valid, non-null pointer.
