Struct Midstate 

pub struct Midstate(pub [u8; 32]);

Output of the SHA256 hash function.

Tuple Fields

0: [u8; 32]

Implementations

impl Midstate

pub const fn from_byte_array(inner: [u8; 32]) -> Self

Construct a new Midstate from the inner value.

pub fn from_slice(sl: &[u8]) -> Result<Midstate, FromSliceError>

Copies a byte slice into the Midstate object.

pub fn to_byte_array(self) -> [u8; 32]

Unwraps the Midstate and returns the underlying byte array.

pub const fn hash_tag(tag: &[u8]) -> Self

Creates midstate for tagged hashes.

Warning: this function is inefficient. It should be only used in const context.

Computes non-finalized hash of sha256(tag) || sha256(tag) for use in sha256t. It’s provided for use with sha256t.

where I: Iterator<Item = Result<u8, HexToBytesError>> + ExactSizeIterator + DoubleEndedIterator,

Produces an object from a byte iterator.

fn from_hex(s: &str) -> Result<Self, Self::Err>

Produces an object from a hex string.

impl FromStr for Midstate

type Err = HexToArrayError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for Midstate

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

type Output = <I as SliceIndex<[u8]>>::Output

The returned type after indexing.

fn index(&self, index: I) -> &Self::Output

Performs the indexing (container[index]) operation.

impl LowerHex for Midstate

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Ord for Midstate

fn cmp(&self, other: &Midstate) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

impl PartialEq for Midstate

fn eq(&self, other: &Midstate) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
