Trait Interface 

pub trait Interface {
    // Required methods
    async fn init(&mut self, cold_boot: bool);
    async fn wait_for_handshake(&mut self);
    async fn wait_for_ready(&mut self);
    async fn transfer(&mut self, buffer: &mut Aligned<A4, [u8]>, tx_len: usize);
}

Physical interface trait for communicating with the ESP chip.

Required Methods

async fn init(&mut self, cold_boot: bool)

Initialize or re-initialize the transport.

async fn wait_for_handshake(&mut self)

Wait for the ESP to indicate readiness for a new transaction.

async fn wait_for_ready(&mut self)

Wait for the ESP to indicate that it has data to send.

async fn transfer(&mut self, buffer: &mut Aligned<A4, [u8]>, tx_len: usize)

Perform a transfer, exchanging data with the ESP chip.

tx_len is the number of bytes in the payload.

The payload bytes contain the valid length of the received buffer.

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.
