Function read_exact_arc

pub async fn read_exact_arc<R: AsyncRead>(
    read: R,
    len: usize,
) -> Result<Arc<[u8]>>

Available on crate features io-util and io only.

Read data from an AsyncRead into an Arc.

This uses Arc::new_uninit_slice and reads into the resulting uninitialized Arc.

Example

use tokio_util::io::read_exact_arc;

let read = tokio::io::repeat(42);

let arc = read_exact_arc(read, 4).await?;

assert_eq!(&arc[..], &[42; 4]);
