Trait KeyscanDriver

pub trait KeyscanDriver {
    // Required method
    async fn scan(&mut self, callback: impl FnMut(KeyChangeEvent));
}

Key scanner driver interface.

The keyscan driver has two roles:

• Scanning the keys
• Determining which hand is currently using the keyboard on a split keyboard

This is because the key scanning circuit often includes a left/right determination circuit.

Required Methods

async fn scan(&mut self, callback: impl FnMut(KeyChangeEvent))

Scans a key and returns the delta from the previous key scan

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.
