Expand description

CPU-level input/output instructions, including inb, outb, etc., and a high level Rust wrapper.

Structs

  • Port
    A readable and writable I/O port over an arbitrary type supporting the InOut interface, which is only u8, u16, or u32.
  • PortReadOnly
    A read-only I/O port over an arbitrary type supporting the InOut interface, which is only u8, u16, and u32.
  • PortWriteOnly
    A write-only I/O port over an arbitrary type supporting the InOut interface, which is only u8, u16, and u32.

Traits

  • PortIn
    This trait is defined for any type which can be read from a port. x86 processors support Port IO for u8, u16 and u32.
  • PortOut
    This trait is defined for any type which can be read from a port. x86 processors support Port IO for u8, u16 and u32.
