Struct SyncShapeTableScope 

pub struct SyncShapeTableScope { /* private fields */ }

RAII guard that installs a shape-table handle on the thread-local slot for the lifetime of the guard.

The previous value (if any) is captured on construction and restored on drop, so nested scopes compose correctly. Used by synchronous VM execution entry points (CLI, unit tests, REPL one-shot) that are not running under a tokio task.

Implementations

impl SyncShapeTableScope

pub fn enter(handle: Arc<ShapeTableHandle>) -> Self

Install handle as the current thread-local shape-table handle, saving the previous value for restoration on drop.

Trait Implementations

impl Drop for SyncShapeTableScope

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
