pub trait IoCapable<T> { }Expand description
Marker trait indicating that an I/O backend supports operations of a certain type.
Different I/O backends can implement this trait to expose only the operations they support.
For example, a PCI configuration space may implement IoCapable<u8>, IoCapable<u16>,
and IoCapable<u32>, but not IoCapable<u64>, while an MMIO region on a 64-bit
system might implement all four.
