Struct MerkleHash 

pub struct MerkleHash(/* private fields */);

SHA-256 Merkle hash (32 bytes).

Args:

• Inner [u8; 32] — raw SHA-256 digest.

Usage:

let hash = MerkleHash::from_bytes([0u8; 32]);
let hex_str = hash.to_string(); // lowercase hex

Implementations

impl MerkleHash

pub const EMPTY: Self

The all-zero hash, used as a sentinel for empty trees.

pub fn from_bytes(bytes: [u8; 32]) -> Self

Wrap raw bytes.

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

Construct from a hex string.

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

Raw bytes.

pub fn to_base64(&self) -> String

Encode as standard base64 (with padding). Used in C2SP checkpoint note body.

pub fn from_base64(s: &str) -> Result<Self, TransparencyError>

Decode from standard base64 (with padding).

pub fn sha256(data: &[u8]) -> Self

Plain SHA-256 (no domain separation). Used for key-ID computation.

Trait Implementations

impl AsRef<[u8]> for MerkleHash

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

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for MerkleHash

fn clone(&self) -> MerkleHash

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for MerkleHash

impl Debug for MerkleHash

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MerkleHash

fn deserialize<D: Deserializer<'de>>(deserializer: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl Display for MerkleHash

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

Formats the value using the given formatter.

impl Eq for MerkleHash

impl Hash for MerkleHash

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for MerkleHash

fn eq(&self, other: &MerkleHash) -> 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.

impl Serialize for MerkleHash

fn serialize<S: Serializer>(&self, serializer: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.
