Struct Lines

pub struct Lines<Direction> { /* private fields */ }

The interface for getting the values of GPIO lines configured for input

Use Chip::request_lines with Options::input or Options::output to configure specific GPIO lines for input or output.

Implementations

impl<Direction: DirectionType> Lines<Direction>

pub async fn get_values<T: AsValuesMut + Send + 'static>( &self, values: T, ) -> Result<T>

Get the value of GPIO lines

The values can only be read if the lines have previously been requested as inputs or outputs using the Chip::request_lines method with Options::input or with Options::output.

impl Lines<Input>

pub async fn read_event(&mut self) -> Result<Event>

Read GPIO events synchronously

The values can only be read if the lines have previously been requested as inputs using the Chip::request_lines method with Options::input.

impl Lines<Output>

pub async fn set_values<T: AsValues + Send + 'static>( &self, values: T, ) -> Result<()>

Set the value of GPIO lines

The value can only be set if the lines have previously been requested as outputs using the Chip::request_lines with Options::output.

Methods from Deref<Target = ValuesInfo>

pub fn chip_name(&self) -> &str

Get associated chip name

pub fn consumer(&self) -> &str

Get consumer string

pub fn lines(&self) -> &[u32]

Get offsets of requested lines

pub fn index(&self) -> &LineMap

Get offset to bit position mapping

Trait Implementations

impl<Direction> Deref for Lines<Direction>

type Target = ValuesInfo

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.
