Enum libp2p::core::multiaddr::multihash::Code

pub enum Code {
    Sha2_256,
    Sha2_512,
    Identity,
}

Default (cryptographically secure) Multihash implementation.

This is a default set of hashing algorithms. Usually applications would use their own subset of algorithms. See the Multihash derive for more information.

Variants

Sha2_256

SHA-256 (32-byte hash size)

Sha2_512

SHA-512 (64-byte hash size)

Identity

Identity hash (max. 64 bytes)
