Struct AnySpiDmaChannel

pub struct AnySpiDmaChannel<'d>(/* private fields */);

Available on crate feature unstable only.

An SPI-compatible type-erased DMA channel.

This struct is a type-erased version of a peripheral singleton. It is useful for creating arrays of peripherals, or avoiding generics. Peripheral singletons can be type erased by using their From implementation.

let any_peripheral = AnySpiDmaChannel::from(peripheral);

Implementations

impl AnySpiDmaChannel<'_>

pub unsafe fn clone_unchecked(&self) -> Self

Unsafely clone this peripheral reference.

Safety

You must ensure that you’re only using one instance of this type at a time.

pub fn reborrow(&mut self) -> AnySpiDmaChannel<'_>

Creates a new peripheral reference with a shorter lifetime.

Use this method if you would like to keep working with the peripheral after you dropped the driver that consumes this.
