}Expand description
Trait which applies to hashes of all types
Associated Types
type Engine: HashEngine
type Engine: HashEngine
A hashing engine which bytes can be serialized into. It is expected
to implement the io::Write trait, and to never return errors under
any conditions.
Associated Constants
const DISPLAY_BACKWARD: bool
const DISPLAY_BACKWARD: bool
Flag indicating whether user-visible serializations of this hash
should be backward. For some reason Satoshi decided this should be
true for Sha256dHash, so here we are.
Required methods
fn from_engine(e: Self::Engine) -> Self
fn from_engine(e: Self::Engine) -> Self
Produce a hash from the current state of a given engine
fn into_inner(self) -> Self::Inner
fn into_inner(self) -> Self::Inner
Unwraps the hash and returns the underlying byte array
Unwraps the hash and returns a reference to the underlying byte array
fn from_inner(inner: Self::Inner) -> Self
fn from_inner(inner: Self::Inner) -> Self
Constructs a hash from the underlying byte array
