[−]Struct libipld::Multihash
A Multihash instance that only supports the basic functionality and no hashing.
With this Multihash implementation you can operate on Multihashes in a generic way, but no hasher implementation is associated with the code.
Example
use tiny_multihash::{Multihash, U64}; const Sha3_256: u64 = 0x16; let digest_bytes = [ 0x16, 0x20, 0x64, 0x4b, 0xcc, 0x7e, 0x56, 0x43, 0x73, 0x04, 0x09, 0x99, 0xaa, 0xc8, 0x9e, 0x76, 0x22, 0xf3, 0xca, 0x71, 0xfb, 0xa1, 0xd9, 0x72, 0xfd, 0x94, 0xa3, 0x1c, 0x3b, 0xfb, 0xf2, 0x4e, 0x39, 0x38, ]; let mh = Multihash::<U64>::from_bytes(&digest_bytes).unwrap(); assert_eq!(mh.code(), Sha3_256); assert_eq!(mh.size(), 32); assert_eq!(mh.digest(), &digest_bytes[2..]);
Implementations
impl<S> Multihash<S> where
S: Size,
S: Size,
pub fn wrap(code: u64, input_digest: &[u8]) -> Result<Multihash<S>, Error>
Wraps the digest in a multihash.
pub fn code(&self) -> u64
Returns the code of the multihash.
pub fn size(&self) -> u8
Returns the size of the digest.
pub fn digest(&self) -> &[u8]
Returns the digest.
pub fn read<R>(r: R) -> Result<Multihash<S>, Error> where
R: Read,
Multihash<S>: Sized,
R: Read,
Multihash<S>: Sized,
Reads a multihash from a byte stream.
pub fn from_bytes(bytes: &[u8]) -> Result<Multihash<S>, Error> where
Multihash<S>: Sized,
Multihash<S>: Sized,
Parses a multihash from a bytes.
You need to make sure the passed in bytes have the correct length. The digest length
needs to match the size
value of the multihash.
pub fn write<W>(&self, w: W) -> Result<(), Error> where
W: Write,
W: Write,
Writes a multihash to a byte stream.
pub fn to_bytes(&self) -> Vec<u8>
Returns the bytes of a multihash.
