Struct simplicity::Amr

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

Annotated Merkle root

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

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

Implementations

impl Amr

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

This is equal to the IMR of the equivalent scribe, converted to a CMR in the usual way for jets.

Trait Implementations

Performs copy-assignment from source.

impl Debug for Amr

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

Formats the value using the given formatter.

impl Display for Amr

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

Formats the value using the given formatter.

impl From<Cmr> for Amr

fn from(cmr: Cmr) -> Self

Converts to this type from the input type.

impl From<Tmr> for Amr

fn from(tmr: Tmr) -> Self

Converts to this type from the input type.

impl FromStr for Amr

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 Amr

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,

impl PartialEq for Amr

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