Struct LineValues 

#[repr(C)]
pub struct LineValues(pub [u8; 64]);

The logical values of the requested lines.

Values are stored as u8, as that is what the uAPI specifies.

0 is inactive with 1 and all other values taken as active.

Values are stored in the same order as the offsets in the HandleRequest.offsets.

Values for input lines are ignored.

Tuple Fields

0: [u8; 64]

Implementations

impl LineValues

pub fn from_slice(s: &[u8]) -> Self

Create values from a slice.

The values are in the same order as HandleRequest.offsets.

pub fn copy_from_slice(&mut self, s: &[u8])

Copy values from an iterable list - in order of requested offsets.

pub fn get(&self, idx: usize) -> u8

Return the value of a line.

Note that the LineValues need to be populated via a call to get_line_values to get values from the underlying hardware.

• idx - The index into the HandleRequest.offsets for the line of interest.

pub fn set(&mut self, idx: usize, value: u8)

Set the value of a line.

Note that this is not applied to hardware until these values are passed to set_line_values.

• idx - The index into the HandleRequest.offsets for the line of interest.
• value - The logical state of the line to be set.

Trait Implementations

impl Clone for LineValues

fn clone(&self) -> LineValues

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for LineValues

impl Debug for LineValues

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

Formats the value using the given formatter.

impl Default for LineValues

fn default() -> Self

Returns the “default value” for a type.

impl Eq for LineValues

impl PartialEq for LineValues

fn eq(&self, other: &LineValues) -> 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.
