Struct gpiocdev::line::Values

pub struct Values(/* private fields */);

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, value: Value) -> &mut Self

Set the value of a line.

pub fn not(&mut self) -> &mut Self

Toggle all values.

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::values().

All lines are set to inactive.

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

An iterator to visit all values.

pub fn iter_mut(&mut self) -> IterMut<'_, LineValue>

An mutating 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<'de> Deserialize<'de> for Values

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'a> FromIterator<&'a u32> for Values

fn from_iter<I: IntoIterator<Item = &'a Offset>>(iter: I) -> Self

Creates a value from an iterator.

impl FromIterator<(u32, Value)> for Values

fn from_iter<I: IntoIterator<Item = (Offset, Value)>>(iter: I) -> Self

Creates a value from an iterator.

impl PartialEq 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.

impl Serialize for Values

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Values

impl StructuralPartialEq for Values
