Module completion 

Completion handles for Swift bridge callbacks.

Synchronous waits are bounded by default. Callback contexts are opaque monotonic tokens backed by a process registry, not addresses. A callback that arrives after timeout/cancellation, or fires more than once, therefore finds no registry entry and returns without touching freed memory.

Structs

AsyncCompletion

Factory for future-based FFI completion handles.

AsyncCompletionFuture

Future returned by AsyncCompletion::create.

SyncCompletion

A blocking completion handler for asynchronous FFI callbacks.

Constants

DEFAULT_TIMEOUT

Default bound for synchronous waits and async completion futures.

TIMEOUT_ENV_VAR

Overrides DEFAULT_TIMEOUT in whole seconds; 0 disables the bound.

TIMEOUT_MESSAGE_PREFIX

Stable prefix for timeout errors.

Functions

default_timeout

Effective process-wide wait bound.

error_from_cstr^⚠

Convert an optional NUL-terminated C string into an owned Rust string.

is_timeout_error

Whether an error came from a bounded wait expiring.

timed_out_context_count

Number of synchronous operations that reached their wait deadline.

Type Aliases

SyncCompletionPtr

Opaque value passed through FFI callbacks.

UnitCompletion

Completion for operations that return only success or an error.
