Enum PitRWMode

#[repr(C)]
pub enum PitRWMode {
    None = 0,
    Least = 1,
    Most = 2,
    Both = 3,
}

The PitRWMode enum represents the access mode of a PIT channel. Reads and writes to the Pit happen over Port-mapped I/O, which happens one byte at a time, but the count values and latch values are two bytes. So the access mode controls which of the two bytes will be read when.

Variants

None = 0

None mode means that no access mode has been set.

Least = 1

Least mode means all reads/writes will read/write the least significant byte.

Most = 2

Most mode means all reads/writes will read/write the most significant byte.

Both = 3

Both mode means first the least significant byte will be read/written, then the next read/write will read/write the most significant byte.

Implementations

impl PitRWMode

pub fn n<REPR: Into<i64>>(value: REPR) -> Option<Self>

Trait Implementations

impl Clone for PitRWMode

fn clone(&self) -> PitRWMode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PitRWMode

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PitRWMode

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<u8> for PitRWMode

Convenience implementation for converting from a u8

fn from(item: u8) -> Self

Converts to this type from the input type.

impl PartialEq for PitRWMode

fn eq(&self, other: &PitRWMode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for PitRWMode

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
