Trait AsyncTouchInputDevice

Source
pub trait AsyncTouchInputDevice {
    type Error;

    // Required method
    fn touches(
        &mut self,
    ) -> impl Future<Output = Result<impl IntoIterator<Item = Touch>, Error<Self::Error>>>;
}
Expand description

Async interface for event-driven operation of touch devices

Required Associated Types§

Source

type Error

Error type from the underlying interface

Required Methods§

Source

fn touches( &mut self, ) -> impl Future<Output = Result<impl IntoIterator<Item = Touch>, Error<Self::Error>>>

Asynchronously wait until touch points are available

Returns an iterator of touch points currently detected. Drivers must track touch IDs across calls to maintain correct phase information.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
