pub trait Input: Into<Self::Buf> {
    type Buf: Buf;
}

Expand description

An input that can be consumed by a decoder.

Buf inputs pass through unchanged. A Vec<u8> transfers its allocation to Bytes without copying its payload. Custom inputs can convert into a Buf.

Borrowing an owned buffer as a slice discards its ability to share decoded byte fields, so slices require an explicit Copying adapter:

use bytes::Bytes;
use commonware_codec::{Decode, Encode};

let encoded = Bytes::from_static(b"hello").encode();
let _ = Bytes::decode_cfg(encoded.as_ref(), &(..).into());

Owning storage is insufficient if the buffer’s byte extraction copies it:

use bytes::Bytes;
use commonware_codec::{Decode, Encode};
use std::io::Cursor;

let encoded = Bytes::from_static(b"hello").encode();
let _ = Bytes::decode_cfg(Cursor::new(encoded), &(..).into());
