Struct GuardedFutureWriter

pub struct GuardedFutureWriter<T, A>
where
    T: Lower + Send + Sync + 'static,
    A: AsAccessor,
{ /* private fields */ }

Available on crate features runtime and component-model and component-model-async only.

A FutureWriter paired with an [Accessor].

This is an RAII wrapper around FutureWriter that ensures it is closed when dropped. This can be created through GuardedFutureWriter::new or FutureWriter::guard.
