Struct muta_protocol::types::Hash

pub struct Hash(_);

Methods

impl Hash

pub fn digest(bytes: Bytes) -> Self

Enter an array of bytes to get a 32-bit hash. Note: sha3 is used for the time being and may be replaced with other hashing algorithms later.

pub fn from_empty() -> Self

pub fn from_bytes(bytes: Bytes) -> ProtocolResult<Self>

Converts the byte array to a Hash type. Note: if you want to compute the hash value of the byte array, you should call fn digest.

pub fn from_hex(s: &str) -> ProtocolResult<Self>

pub fn as_bytes(&self) -> Bytes

pub fn as_hex(&self) -> String
