Struct LineValues

#[repr(C)]
pub struct LineValues(/* private fields */);

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.

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.

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

Performs copy-assignment from source.

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 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.
