Struct stm32_eth::dma::RxRing

pub struct RxRing<'a> { /* private fields */ }

Rx DMA state

Implementations

impl<'a> RxRing<'a>

pub fn running_state(&self) -> RunningState

Get current RunningState

pub fn next_entry_available(&self) -> bool

Check if we can receive a new packet

pub fn recv_next( &mut self, packet_id: Option<PacketId> ) -> Result<RxPacket<'_>, RxError>

Receive the next packet (if any is ready), or return Err immediately.

pub async fn recv(&mut self, packet_id: Option<PacketId>) -> RxPacket<'_>

Receive the next packet.

The returned RxPacket can be used as a slice, and will contain the ethernet data.

impl<'a> RxRing<'a>

pub fn timestamp( &self, id: &PacketId ) -> Result<Option<Timestamp>, PacketIdNotFound>

Get the timestamp for a specific ID
