Trait Interface 

pub trait Interface {
    // Required methods
    async fn wait_for_handshake(&mut self);
    async fn wait_for_ready(&mut self);
    async fn transfer(&mut self, rx: &mut [u8], tx: &[u8]);
}

Physical interface trait for communicating with the ESP chip.

Required Methods

async fn wait_for_handshake(&mut self)

Wait for the HANDSHAKE signal indicating the ESP is ready for a new transaction.

async fn wait_for_ready(&mut self)

Wait for the READY signal indicating the ESP has data to send.

async fn transfer(&mut self, rx: &mut [u8], tx: &[u8])

Perform a SPI transfer, exchanging data with the ESP chip.

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.
