Struct gpiocdev::async::tokio::AsyncChip

pub struct AsyncChip(_);

Async wrapper around Chip for the tokio reactor.

Example

use gpiocdev::chip::Chip;
use gpiocdev::r#async::tokio::AsyncChip;

let chip = Chip::from_path("/dev/gpiochip0")?;
let achip = AsyncChip::new(chip);
let evt = achip.read_line_info_change_event().await?;

Implementations

impl AsyncChip

pub fn new(chip: Chip) -> Self

Create a Tokio wrapper for a Chip.

pub async fn read_line_info_change_event(&self) -> Result<InfoChangeEvent>

Async form of Chip::read_line_info_change_event.

Example

use gpiocdev::r#async::tokio::AsyncChip;

let chip = Chip::from_path("/dev/gpiochip0")?;
let achip = AsyncChip::new(chip);
let evt = achip.read_line_info_change_event().await?;

pub fn info_change_events(&self) -> InfoChangeStream<'_>

Async form of Chip::info_change_events.

Example

use gpiocdev::r#async::tokio::AsyncChip;
use tokio_stream::StreamExt;

let chip = Chip::from_path("/dev/gpiochip0")?;
let achip = AsyncChip::new(chip);
let mut events = achip.info_change_events();
while let Ok(evt) = events.next().await.unwrap() {
    // process event...
}

Trait Implementations

impl AsRef<Chip> for AsyncChip

fn as_ref(&self) -> &Chip

Converts this type into a shared reference of the (usually inferred) input type.
