Struct SmoltcpAdapter

pub struct SmoltcpAdapter<'a, D: NetworkDriver> {
    driver: &'a mut D,
    rx_buffer: [u8; 2048],
    rx_len: usize,
}

Adapter bridging NetworkDriver to smoltcp Device trait.

This adapter uses a simple design where:

• RX: Buffers received data internally, RxToken references it
• TX: TxToken writes directly via the driver

Fields

driver: &'a mut D

rx_buffer: [u8; 2048]

Temporary buffer for received packet

rx_len: usize

Length of data in rx_buffer (0 if no pending packet)

Implementations

impl<'a, D: NetworkDriver> SmoltcpAdapter<'a, D>

pub fn new(driver: &'a mut D) -> Self

pub fn poll_receive(&mut self)

Try to receive a packet into our internal buffer. Called before polling smoltcp.

pub fn refill_rx(&mut self)

Refill RX queue. Called in main loop Phase 1.

pub fn collect_tx(&mut self)

Collect TX completions. Called in main loop Phase 5.

Trait Implementations

impl<'a, D: NetworkDriver> Device for SmoltcpAdapter<'a, D>

type RxToken<'b> = RxToken where Self: 'b

type TxToken<'b> = TxToken<'b, D> where Self: 'b

fn receive( &mut self, _timestamp: Instant, ) -> Option<(Self::RxToken<'_>, Self::TxToken<'_>)>

Construct a token pair consisting of one receive token and one transmit token.

fn transmit(&mut self, _timestamp: Instant) -> Option<Self::TxToken<'_>>

Construct a transmit token.
