Module dynamics 

Thread-local dynamic variable binding stack.

binding forms push a frame onto BINDING_STACK for the duration of their body; the RAII BindingGuard pops it on drop (handles both normal return and panics).

Structs

BindingGuard

Pops the innermost binding frame when dropped.

Functions

capture_current

Snapshot the current thread’s entire binding stack (for conveyance into a child thread, e.g. future).

deref_var

Check the thread-local stack first (innermost frame wins); fall back to the root binding stored in the Var itself.

install_frames

Install a previously captured snapshot on the current (new) thread.

is_thread_bound

True if var has any thread-local binding on this thread.

push_frame

Push a new dynamic binding frame; return a guard that pops it on drop.

set_thread_local

Set the innermost thread-local binding for var. Returns false if no thread-local binding exists (caller should fall back to setting the root).

trace_current

Trace all values in the current thread’s binding stack as GC roots. Call this during the GC root enumeration phase.

var_key_of

Type Aliases

VarKey

Opaque key for a Var in the binding stack (pointer identity). Stable because the GC is non-moving.
