Module resource 

The Resource trait for I/O handles and other closeable resources.

Resources are ref-counted with Arc (NOT GcPtr) so that they get deterministic cleanup when the last reference drops. The GC has no finalizers, so GcPtr would leak file descriptors.

Structs

A wrapper around Arc<dyn Resource> that provides Clone and Debug.

Traits
