Struct EmacDriverState 

pub struct EmacDriverState { /* private fields */ }

Shared state for the embassy-net driver.

Holds the RX, TX, and link wakers plus the cached link state. Place in a static so it can be reached from the EMAC ISR.

Implementations

impl EmacDriverState

pub const fn new() -> Self

Create a new state with link initially down.

pub fn irq_counters(&self) -> IrqCounters

Diagnostic counters from the ISR.

pub fn driver_counters(&self) -> DriverCounters

Diagnostic counters from Driver::receive / Driver::transmit and the matching tokens.

pub fn link_state(&self) -> LinkState

Read the cached link state.

pub fn set_link_state(&self, state: LinkState)

Update the cached link state and wake stack tasks.

pub fn set_link_up(&self)

Mark the link as up and wake the stack.

pub fn set_link_down(&self)

Mark the link as down and wake the stack.

pub fn on_interrupt_status(&self, status: InterruptStatus)

Wake RX/TX tasks based on a snapshot of the DMA interrupt status.

pub fn handle_emac_interrupt(&self)

Read the DMA status register, clear the interrupts, and wake any tasks waiting on RX or TX.

Does not wake link_waker — link state isn’t reflected in DMASTATUS and is updated separately by whatever PHY-polling task calls set_link_up / set_link_down. That path takes care of waking link-state observers itself.

Intended to be called from the EMAC ISR. Touches only memory- mapped EMAC registers and the embedded wakers, so there is no aliasing concern with the EmacDriver holding a raw pointer to the Emac state.

Trait Implementations

impl Default for EmacDriverState

fn default() -> Self

Returns the “default value” for a type.
