Trait libipld::cid::multihash::Digest

pub trait Digest<S>: 'static + AsRef<[u8]> + AsMut<[u8]> + From<GenericArray<u8, S>> + Into<GenericArray<u8, S>> + Clone + Hash + Debug + Default + Eq + Send + Sync where
    S: Size, {
    fn size(&self) -> u8 { ... }
    fn wrap(digest: &[u8]) -> Result<Self, Error> { ... }
    fn from_reader<R>(r: R) -> Result<Self, Error>
    where
        R: Read,
    { ... }
}

Stack allocated digest trait.

Provided methods

fn size(&self) -> u8

Size of the digest.

fn wrap(digest: &[u8]) -> Result<Self, Error>

Wraps the digest bytes.

fn from_reader<R>(r: R) -> Result<Self, Error> where
    R: Read, 

Reads a multihash digest from a byte stream that contains the digest prefixed with the size.

The byte stream must not contain the code as prefix.
