Struct Shared 

pub struct Shared<P>(/* private fields */);

One bridge, held by everything that needs it.

The concentrator driver takes its SPI device and its reset pin as two values it owns, and over USB both are the same bridge. This is how they share it.

Implementations

impl<P: Read + Write> Shared<P>

pub fn new(bridge: Bridge<P>) -> Shared<P>

Shares a bridge.

Arguments

• bridge - the bridge to share.

Returns

A handle, which clones cheaply.

pub fn concentrator(&self) -> BridgeSpi<P>

The SPI device the concentrator answers on.

Returns

A device the driver takes, carrying every frame to the concentrator and the front ends behind it.

pub fn listener(&self) -> BridgeSpi<P>

The SPI device the radio beside the concentrator answers on.

Returns

A device carrying every frame to that radio, which is what a carrier check drives.

pub fn pin(&self, pin: u8) -> BridgePin<P>

One of the card’s pins, as a pin the driver drives.

Arguments

• pin - which one, such as PIN_RESET.

Returns

The pin.

pub fn with<T>( &self, with: impl FnOnce(&mut Bridge<P>) -> Result<T, UsbError>, ) -> Result<T, UsbError>

Does something with the bridge itself, holding it for the duration.

Arguments

• with - what to do.

Returns

Whatever it returned.

Errors

UsbError::Poisoned when another holder panicked, and whatever with returned.

Trait Implementations

impl<P> Clone for Shared<P>

fn clone(&self) -> Shared<P>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
