Function bao::decode::decode

pub fn decode(
    encoded: &[u8],
    output: &mut [u8],
    hash: &Hash
) -> Result<usize, Error>

Decode a combined mode encoding to an output slice. The slice must be at least the length reported by parse_and_check_content_len. This returns the number of decoded bytes if successful, or an error if the encoding doesn’t match the hash.

If the std feature is enabled, as it is by default, this will use multiple threads via Rayon.

Example

let input = b"foobar";
let (hash, encoded) = bao::encode::encode_to_vec(input);
// Note that if you're allocating a new Vec like this, decode_to_vec is more convenient.
let mut output = vec![0; input.len()];
let content_len = bao::decode::decode(&encoded, &mut output, &hash).unwrap();
assert_eq!(input.len(), content_len);
assert_eq!(input, &output[..content_len]);
