ariel_os::sensors::sensor

Struct ReadingWaiter 

pub struct ReadingWaiter { /* private fields */ }
Available on crate feature sensors only.
Expand description

Future returned by Sensor::wait_for_reading().

Implementations§

§

impl ReadingWaiter

pub fn new( fut: ReceiveFuture<'static, Result<Samples, ReadingError>>, ) -> ReadingWaiter ⓘ

Creates a new Future to send back Samples.

§Note

For sensor driver implementors only.

pub fn new_err(err: ReadingError) -> ReadingWaiter ⓘ

Creates a new Future to send back an error that happened when obtaining a reading.

§Note

For sensor driver implementors only.

Trait Implementations§

§

impl Future for ReadingWaiter
