Struct NullRx

pub struct NullRx<T>(/* private fields */);

A codelet which drops all messages it receives.

Trait Implementations

impl<T: Send + Sync + Clone> Codelet for NullRx<T>

type Status = DefaultStatus

Status code used to indicate health of codelet

type Config = ()

Type used for configuration

type Rx = DoubleBufferRx<T>

Type holding all receiving (RX) endpoints

type Tx = ()

Type holding all transmitting (TX) endpoints

fn build_bundles(_cfg: &Self::Config) -> (Self::Rx, Self::Tx)

Constructs channel bundles

fn step( &mut self, _: &Context<'_, Self>, rx: &mut Self::Rx, _: &mut Self::Tx, ) -> Outcome

Step is executed periodically after the codelet is started and while it is not paused.

fn start( &mut self, _cx: &Context<'_, Self>, _rx: &mut Self::Rx, _tx: &mut Self::Tx, ) -> Result<Self::Status, Report>

Start is guaranteed to be called first. Start may be called again after stop was called.

fn stop( &mut self, _cx: &Context<'_, Self>, _rx: &mut Self::Rx, _tx: &mut Self::Tx, ) -> Result<Self::Status, Report>

Stop is guaranteed to be called at the end if start was called.

fn pause(&mut self) -> Result<Self::Status, Report>

Pause may be called to suspend stepping.

fn resume(&mut self) -> Result<Self::Status, Report>

Resume is called to resume stepping. Note that stop may also be called while the codelet is paused to stop the codelet completely instead of resuming stepping.

impl<T> Default for NullRx<T>

fn default() -> Self

Returns the “default value” for a type.
