Buffer Types for embedded-io
The buffered-io
crate implements buffering for the embedded-io
/embedded-io-async
Read
and Write
traits.
Example
#[cfg(feature = "async")]
tokio_test::block_on(async {
use buffered_io::asynch::BufferedWrite;
use embedded_io_async::Write;
let uart_tx = Vec::new(); // The underlying uart peripheral implementing Write to where buffered bytes are written
let mut write_buf = [0; 120];
let mut buffering = BufferedWrite::new(uart_tx, &mut write_buf);
buffering.write(b"hello").await.unwrap(); // This write is buffered
buffering.write(b" ").await.unwrap(); // This write is also buffered
buffering.write(b"world").await.unwrap(); // This write is also buffered
buffering.flush().await.unwrap(); // The string "hello world" is written to uart in one write
})
