Struct sunrise_kernel::i386::pio::Pio

pub struct Pio<T> {
    port: u16,
    value: PhantomData<T>,
}

Port IO accessor.

Fields

port: u16

The io port address.

value: PhantomData<T>

The width of the port.

Implementations

impl<T> Pio<T>

pub fn new(port: u16) -> Pio<T>

Create a PIO from a given port

Trait Implementations

impl<T> Clone for Pio<T> where
    T: Clone, 

fn clone(&self) -> Pio<T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T> Copy for Pio<T> where
    T: Copy, 

impl<T> Debug for Pio<T> where
    T: Debug, 

fn fmt(&self, f: &mut Formatter) -> Result<(), Error>

Formats the value using the given formatter.

impl Io for Pio<u32>

Read/Write for doubleword PIO

type Value = u32

The width of the IO access. Should be a primitive type like u8, u16, u32...

fn read(&self) -> u32

Read

fn write(&mut self, value: u32)

Write

fn readf(&self, flags: Self::Value) -> bool where
    Self::Value: PartialEq<Self::Value>,
    Self::Value: BitAnd<Self::Value>,
    <Self::Value as BitAnd<Self::Value>>::Output == Self::Value, 

Read from this Io, and mask the value with flags.

fn writef(&mut self, flags: Self::Value, value: bool) where
    Self::Value: PartialEq<Self::Value>,
    Self::Value: BitAnd<Self::Value>,
    Self::Value: BitOr<Self::Value>,
    Self::Value: Not,
    <Self::Value as BitAnd<Self::Value>>::Output == Self::Value,
    <Self::Value as BitOr<Self::Value>>::Output == Self::Value,
    <Self::Value as Not>::Output == Self::Value, 

Mask value with flags, and write it to this device address. Note that this causes a read!

impl Io for Pio<u8>

Read/Write for byte PIO

type Value = u8

The width of the IO access. Should be a primitive type like u8, u16, u32...

fn read(&self) -> u8

Read

fn write(&mut self, value: u8)

Write

fn readf(&self, flags: Self::Value) -> bool where

    Self::Value: BitAnd<Self::Value>,
    <Self::Value as BitAnd<Self::Value>>::Output == Self::Value, 

Read from this Io, and mask the value with flags.

fn writef(&mut self, flags: Self::Value, value: bool) where
    Self::Value: PartialEq<Self::Value>,
    Self::Value: BitAnd<Self::Value>,

    Self::Value: Not,
    <Self::Value as BitAnd<Self::Value>>::Output == Self::Value,
    <Self::Value as BitOr<Self::Value>>::Output == Self::Value,
    <Self::Value as Not>::Output == Self::Value, 

Mask value with flags, and write it to this device address. Note that this causes a read!
