Crate holo_hash

Defines HoloHash and its various HashTypes

Re-exports

• pub use hash_type::HashType;
• pub use hash_type::PrimitiveHashType;

Modules

• encode_raw
  By default, disable string encoding and just display raw bytes
• error
  HoloHash Error Type.
• hash_type
  Defines the prefixes for the various HashTypes, as well as the traits which unify them

Macros

• 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<SerializedBytes>, and uses a PrimitiveHashType

Structs

• CompositeHashConversionError
  Error converting a composite hash into a subset composite hash, due to type mismatch
• EntryHashes
  A newtype for a collection of EntryHashes, needed for some wasm return types.
• HashConversionError
  Error converting a composite hash into a primitive one, due to type mismatch
• 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.

Enums

• AnyDhtHashPrimitive
  The primitive hash types represented by this composite hash
• AnyLinkableHashPrimitive
  The primitive hash types represented by this composite hash
• HashableContentBytes
  HashableContent can be expressed as “content”, or “prehashed”, which affects how a HoloHashed type will be constructed from it.

Constants

• 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

Traits

• 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.

Type Aliases

• ActionHash
  The hash of an action
• 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 ActionHash
• AnyLinkableHash
  The hash of anything linkable.
• DhtOpHash
  The hash of a DhtOp’s “unique form” representation
• DnaHash
  The hash of a DnaDef
• EntryHash
  The hash of an Entry.
• ExternalHash
  The hash of some external data that can’t or doesn’t exist on the DHT.
• HoloHashOf
  A convenience type, for specifying a hash by HashableContent rather than by its HashType
• NetIdHash
  The hash of a network ID
• OpBasis
  Alias for AnyLinkableHash. This hash forms the notion of the “basis hash” of an op.
• WasmHash
  The hash of some wasm bytecode
• ZomeCallSigningKey
  A public key of a pair of signing keys for signing zome calls.
