proc `$`(mh: MultiHash): string {....raises: [], tags: [], forbids: [].}: Return string representation of MultiHash value. Source Edit
proc `==`(a: MultiHash; b: MultiHash): bool {....raises: [], tags: [], forbids: [].}: Compares MultiHashes a and b, returns true if hashes are equal, false otherwise. Source Edit
proc `==`[T](mdigest: MDigest[T]; mh: MultiHash): bool {.inline, ...raises: [].}: Compares MultiHash with nimcrypto's MDigestT, returns true if hashes are equal, false otherwise. Source Edit
proc `==`[T](mh: MultiHash; mdigest: MDigest[T]): bool {....raises: [].}: Compares MultiHash with nimcrypto's MDigestT, returns true if hashes are equal, false otherwise. Source Edit
proc base58(value: MultiHash): string {....raises: [], tags: [], forbids: [].}: Return Base58 encoded string representation of MultiHash value. Source Edit
proc decode(mhtype: typedesc[MultiHash]; data: openArray[byte]; mhash: var MultiHash): MhResult[int] {....raises: [].}: Decode MultiHash value from array of bytes data.

On success decoded MultiHash will be stored into mhash and number of bytes consumed will be returned.

On error -1 will be returned.
