Struct UserIO

Source 
pub struct UserIO<Interface: IoInterface, Access: IoAccessKind = ReadWrite, OwnKind: OwnStrictness = Owned> { /* private fields */ }
Expand description

Userspace access to IO devices

§Currently Supported Interfaces

  • CpuIO CPU IO Port bus access

§Why use this type?

UserIO represents an ‘owned’ access over some IO device on the system. This is important because future processes will not be able to access this IO device until it is dropped.

This type also attempts to implment the interface to access such hardware device in the safest possible way.
