Hashing trait

Required Methods

fn hash(data: &[u8]) -> Self

Hash the given data

fn as_bytes(&self) -> &[u8]

Get the bytes of the hash

fn from_bytes(bytes: &[u8]) -> StacksResult<Self>

Attempt to create a hash from the given bytes

Provided Methods

fn new(value: impl AsRef<[u8]>) -> Self

Create a hash from the given bytes

fn zeroes() -> Self

Create a zeroed hash

fn checksum(&self) -> [u8; 4]

Get the checksum of the hash

fn from_hex(data: impl AsRef<str>) -> StacksResult<Self>

Attempt to create a hash from the given hex bytes

fn to_hex(&self) -> String

Get the hex representation of the hash

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
