pub use hash_b64::*;

pub use hash_type::HashType;

encode	Include nice string encoding methods and From impls
error	HoloHash Error Type.
fixt
hash_b64	Implements base-64 serialization for HoloHashes
hash_type	Defines the prefixes for the various HashTypes, as well as the traits which unify them

assert_length	Helper for ensuring the the proper number of bytes is used in various situations
impl_hashable_content	A default HashableContent implementation, suitable for content which is already TryInto, and uses a PrimitiveHashType

EntryHashes	A newtype for a collection of EntryHashes, needed for some wasm return types.
HoloHash	A HoloHash contains a vector of 36 bytes representing a 32-byte blake2b hash plus 4 bytes representing a DHT location. It also contains a zero-sized type which specifies what it is a hash of.
HoloHashed	Represents some piece of content along with its hash representation, so that hashes need not be calculated multiple times. Provides an easy constructor which consumes the content.

HashableContent can be expressed as “content”, or “prehashed”, which affects how a HoloHashed type will be constructed from it.

HOLO_HASH_CORE_LEN	Length of the core bytes (32)
HOLO_HASH_FULL_LEN	Length of the full HoloHash bytes (39 = 3 + 32 + 4)
HOLO_HASH_LOC_LEN	Length of the location bytes (4)
HOLO_HASH_PREFIX_LEN	Length of the prefix bytes (3)
HOLO_HASH_UNTYPED_LEN	Length of the core bytes + the loc bytes (36 = 32 + 4), i.e. everything except the type prefix

HasHash	Anything which has an owned HoloHashOf.
HashableContent	Any implementor of HashableContent may be used in a HoloHashed to pair data with its HoloHash representation. It also has an associated HashType.
PrimitiveHashType	A PrimitiveHashType is one with a multihash prefix. In contrast, a non-primitive hash type could be one of several primitive types, e.g. an `AnyDhtHash` can represent one of three primitive types.

AgentPubKey	An Agent public signing key. Not really a hash, more of an “identity hash”.
AnyDhtHash	The hash of anything referrable in the DHT. This is a composite of either an EntryHash or a HeaderHash
DhtOpHash	The hash of a DhtOp’s “unique form” representation
DnaHash	The hash of a DnaDef
EntryHash	The hash of an Entry.
HeaderHash	The hash of a Header
HoloHashOf	A convenience type, for specifying a hash by HashableContent rather than by its HashType
NetIdHash	The hash of a network ID
WasmHash	The hash of some wasm bytecode
