}Expand description
Trait which applies to hashes of all types.
Required Associated Types§
sourcetype 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.
Required Associated Constants§
Provided Associated Constants§
sourceconst DISPLAY_BACKWARD: bool = false
const DISPLAY_BACKWARD: bool = false
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§
sourcefn from_engine(e: Self::Engine) -> Self
fn from_engine(e: Self::Engine) -> Self
Produces a hash from the current state of a given engine.
sourcefn from_slice(sl: &[u8]) -> Result<Self, Error>
fn from_slice(sl: &[u8]) -> Result<Self, Error>
Copies a byte slice into a hash object.
sourcefn to_byte_array(self) -> Self::Bytes
fn to_byte_array(self) -> Self::Bytes
Returns the underlying byte array.
sourcefn as_byte_array(&self) -> &Self::Bytes
fn as_byte_array(&self) -> &Self::Bytes
Returns a reference to the underlying byte array.
sourcefn from_byte_array(bytes: Self::Bytes) -> Self
fn from_byte_array(bytes: Self::Bytes) -> Self
Constructs a hash from the underlying byte array.
Provided Methods§
Object Safety§
This trait is not object safe.
