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

Converts the given tagged hash into a byte array

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

Converts the given tagged hash into a byte array

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

Converts the given tagged hash into a byte array

impl Tmr

pub const TWO_TWO_N: [Tmr; 32]

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

pub const BUFFER8_TWO_N_PLUS_ONE: [Tmr; 16]

The TMRs of the types (TWO^8)^<(2^(N + 1)) for small values of n

pub const CTX8: Tmr

The TMR of the Ctx8 type used by the SHA256 jets.

pub const fn unit() -> Tmr

The TMR for the unit type

pub fn successor(self) -> Tmr

The TMR for the successor of a type.

Given a type X, we define its successor S X as 1 + X. In Rust notation this would be Option<X>.

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

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

pub const fn sum_unoptimized(tmr1: Tmr, tmr2: Tmr) -> Tmr

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

This function is slow but can be used in a const context. If you do not need to run in a const context, use Self::sum instead.

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

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

pub const fn product_unoptimized(tmr1: Tmr, tmr2: Tmr) -> Tmr

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

This function is slow but can be used in a const context. If you do not need to run in a const context, use Self::product instead.
