Struct Ihr

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

Identity Hash Root

A Merkle root that commits to a node’s Imr (which recursively commits to its childrens’ Imrs) as well as its source and target types.

Uniquely identifies a program’s structure in terms of combinators at redemption time.

Implementations

impl Ihr

pub fn update(self, left: Self, right: Self) -> Self

Extend the given tagged hash by the given left and right hashes.

The hash self is taken as initial value, left and right hash are combined to create a 512-bit block, and the compression function is run once

pub fn update_1(self, right: Self) -> Self

Extend the given tagged hash by 256 bits of zeroes and the right hash.

The hash self is taken as initial value, 256 bits of zeroes and right hash are combined to create a 512-bit block, and the compression function is run once

pub fn update_with_weight(self, left_weight: u64, right: Self) -> Self

Updates the given tagged hash with given left cost and right hash.

The cost is serialized as the last 64 bits in the left block

pub fn update_fail_entropy(self, entropy: FailEntropy) -> Self

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

Converts the given tagged hash into a byte array

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

Converts the given tagged hash into a byte array

impl Ihr

pub fn from_imr(imr: Imr, ty: &FinalArrow) -> Ihr

Construct an IHR from its components: an IMR and the source and target types.

Trait Implementations

impl AsRef<[u8]> for Ihr

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

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

impl Clone for Ihr

fn clone(&self) -> Ihr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Ihr

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

Formats the value using the given formatter.

impl Display for Ihr

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

Formats the value using the given formatter.

impl From<Cmr> for Ihr

fn from(cmr: Cmr) -> Self

Converts to this type from the input type.

impl From<Tmr> for Ihr

fn from(tmr: Tmr) -> Self

Converts to this type from the input type.

impl FromStr for Ihr

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 Ihr

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 Ord for Ihr

fn cmp(&self, other: &Ihr) -> 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.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Ihr

fn eq(&self, other: &Ihr) -> 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 PartialOrd for Ihr

fn partial_cmp(&self, other: &Ihr) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
