Struct gpiocdev::line::Values

pub struct Values(_);

A collection of line values.

Lines are identified by their offset.

Implementations

impl Values

pub fn get(&self, offset: Offset) -> Option<Value>

Get the value of a line.

pub fn set(&mut self, offset: Offset, val: Value) -> &mut Self

Set the value of a line.

pub fn toggle(&mut self, offset: Offset)

Toggle the value of a line.

If not already set then sets the line active.

pub fn unset(&mut self, offset: Offset)

Remove any value setting for a line.

pub fn len(&self) -> usize

The number of lines for which values are contained in this set.

pub fn is_empty(&self) -> bool

Return true if the values is empty.

pub fn from_offsets(offsets: &[Offset]) -> Values

Construct a Values collection for a set of line offsets.

Typically used to create a values template to be populated via a call to crate::request::Request::values().

All lines are set to inactive.

pub fn iter(&self) -> Iter<'_, Offset, Value>

An iterator to visit all values.

Trait Implementations

impl Debug for Values

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

Formats the value using the given formatter.

impl Default for Values

fn default() -> Values

Returns the “default value” for a type.

impl PartialEq<Values> for Values

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

This method tests for self and other values to be equal, and is used by ==.

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

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