Struct simplicity::Imr

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

Identity Merkle root

A Merkle root that commits to a node’s combinator, its witness data (if present), its source and target types, and recursively its children.

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

Implementations

impl Imr

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 Imr

pub fn compute_pass2(first_pass: FirstPassImr, ty: &FinalArrow) -> Imr

Do the second pass of the IMR computation. This must be called on the result of first pass.

Trait Implementations

impl AsRef<[u8]> for Imr

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

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

impl Clone for Imr

fn clone(&self) -> Imr

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Imr

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

Formats the value using the given formatter.

impl Display for Imr

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

Formats the value using the given formatter.

impl From<Cmr> for Imr

fn from(cmr: Cmr) -> Self

Converts to this type from the input type.

impl From<Tmr> for Imr

fn from(tmr: Tmr) -> Self

Converts to this type from the input type.

impl FromStr for Imr

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 Imr

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 Imr

fn cmp(&self, other: &Imr) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for Imr

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for Imr

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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