sodiumScope<R> function

R sodiumScope<R>(LibSodiumFFI sodium, R body(SodiumScope scope))

Runs body in a fresh SodiumScope, disposing everything the scope still owns, in reverse (LIFO) order, when body returns or throws.

This is synchronous by design: the operations that use it never allocate across an await, so there is no Future branch. The value produced by body is returned unchanged.

Implementation

R sodiumScope<R>(LibSodiumFFI sodium, R Function(SodiumScope scope) body) {
  final scope = SodiumScope._(sodium);
  try {
    return body(scope);
  } finally {
    scope._releaseAll();
  }
}
