Struct simplicity::Tmr

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

Type Merkle root

A Merkle root that commits to a type’s primitive (unit, sum, product) and recursively its sub-types.

Uniquely identifies a type.

Implementations

impl Tmr

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 Tmr

pub const UNIT_IV: Tmr = _

The IV for a TMR of a unit type

pub const SUM_IV: Tmr = _

The IV for a TMR of a sum type

pub const PRODUCT_IV: Tmr = _

The IV for a TMR of a product type

pub const POWERS_OF_TWO: [Tmr; 32] = _

The TMRs of the types TWO^(2^n) for small values of n

pub const fn unit() -> Tmr

The TMR for the unit type

pub fn sum(tmr1: Tmr, tmr2: Tmr) -> Tmr

The TMR for the sum of two types, whose TMRs are given

pub fn product(tmr1: Tmr, tmr2: Tmr) -> Tmr

The TMR for the product of two types, whose TMRs are given

Trait Implementations

impl AsRef<[u8]> for Tmr

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

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

impl Clone for Tmr

fn clone(&self) -> Tmr

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Tmr

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

Formats the value using the given formatter.

impl Display for Tmr

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

Formats the value using the given formatter.

impl From<Tmr> for Amr

fn from(tmr: Tmr) -> Self

Converts to this type from the input type.

impl From<Tmr> for Cmr

fn from(tmr: Tmr) -> 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 Tmr

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 Tmr

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 Tmr

fn cmp(&self, other: &Tmr) -> 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 Tmr

fn eq(&self, other: &Tmr) -> 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 Tmr

fn partial_cmp(&self, other: &Tmr) -> 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.
