Struct BlockingAsync

Source
pub struct BlockingAsync<T> { /* private fields */ }
Expand description

Wrapper that implements async traits using blocking implementations.

This allows driver writers to depend on the async traits while still supporting embedded-hal peripheral implementations.

BlockingAsync will implement any async trait that maps to embedded-hal traits implemented for the wrapped driver.

Driver users are then free to choose which implementation that is available to them.

Implementations§

Read words from the slave. Read more
Source§

async fn transfer( &mut self, read: &mut [u8], write: &[u8], ) -> Result<(), Self::Error>
