Trait TouchInputDevice

pub trait TouchInputDevice {
    type Error;

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

Blocking interface for touch devices.

Required Associated Types

Error type from the underlying interface

Required Methods

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

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.
