Struct lsx::sha256::BufSha256

pub struct BufSha256 { /* fields omitted */ }

A SHA-256 state, including a buffer to allow non-block-sized inputs.

                        characters.";

                        contiguous in memory with the other one.";
const DATA_3: &[u8] = b"Have a little more text!";
let mut hasher = BufSha256::new();
hasher.update(DATA_1);
hasher.update(DATA_2);
