Struct MerkleHashOrchard

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

A node in the Orchard note commitment tree.

Implementations

impl MerkleHashOrchard

pub fn new(data: [u8; 32]) -> Self

Creates a new instance from a fixed-size byte array.

This is the primary constructor when you have an exact-sized array available.

pub fn len(&self) -> usize

Returns the length of this blob in bytes.

This will always return $size for this type.

pub fn is_empty(&self) -> bool

Returns true if this blob contains no bytes.

This will always return false for this type (unless $size is 0).

pub fn to_vec(&self) -> Vec<u8>

Converts this blob to a Vec<u8>, creating a copy of the data.

pub fn as_slice(&self) -> &[u8]

Exposes the underlying byte array as a slice.

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

Exposes the underlying byte array.

pub fn from_slice(data: &[u8]) -> Result<Self, TryFromSliceError>

Creates an instance from a slice of bytes.

Errors

Returns an error if the slice’s length doesn’t match the expected size ($size).

pub fn from_vec(data: Vec<u8>) -> Result<Self, TryFromSliceError>

Creates an instance from a Vec<u8>.

Errors

Returns an error if the vector’s length doesn’t match the expected size ($size).

pub fn from_hex(hex: &str) -> Result<Self, HexParseError>

Parses an instance from a hex string.

pub fn from_reversed_hex(hex: &str) -> Result<Self, HexParseError>

Parses an instance from a hex string in reversed byte order, such as is used for transaction identifiers and block hashes.

pub fn to_hex(&self) -> String

Formats the bytes of this object as a hex string.

Trait Implementations

impl AsRef<[u8]> for MerkleHashOrchard

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

impl Clone for MerkleHashOrchard

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MerkleHashOrchard

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

Formats the value using the given formatter.

impl From<&[u8]> for MerkleHashOrchard

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

Converts to this type from the input type.

impl From<&MerkleHashOrchard> for CBOR

fn from(data: &MerkleHashOrchard) -> Self

Converts to this type from the input type.

impl From<&MerkleHashOrchard> for Vec<u8>

fn from(blob: &MerkleHashOrchard) -> Vec<u8>

impl Hash for MerkleHashOrchard

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 MerkleHashOrchard

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