Struct Tryte3 

pub struct Tryte3(/* private fields */);

A balanced ternary byte consisting of 3 trits.

Value Range

A Tryte3 can represent values from -13 to +13:

Value = t0 * 1 + t1 * 3 + t2 * 9
Min: -1 - 3 - 9 = -13
Max: +1 + 3 + 9 = +13

Internal Representation

Stored as a single u8 with the following encoding:

• Bits 0-1: trit 0 (least significant)
• Bits 2-3: trit 1
• Bits 4-5: trit 2 (most significant)

Each trit is encoded as: 0=N(-1), 1=Z(0), 2=P(+1)

Examples

use trit_vsa::Tryte3;

let t = Tryte3::from_value(5).unwrap();
assert_eq!(t.value(), 5);

// Decompose into trits: 5 = -1 + (-1)*3 + 1*9 = -1 - 3 + 9
let trits = t.to_trits();
assert_eq!(trits[0].value(), -1);  // t0 = -1
assert_eq!(trits[1].value(), -1);  // t1 = -1
assert_eq!(trits[2].value(), 1);   // t2 = +1

Implementations

impl Tryte3

pub fn from_value(value: i32) -> Result<Self>

Create a tryte from an integer value.

Arguments

• value - Integer value (-13 to +13)

Errors

Returns TernaryError::InvalidTryteValue if value is outside range.

Examples

use trit_vsa::Tryte3;

let t = Tryte3::from_value(7).unwrap();
assert_eq!(t.value(), 7);

assert!(Tryte3::from_value(14).is_err());
assert!(Tryte3::from_value(-14).is_err());

pub fn from_trits(trits: [Trit; 3]) -> Self

Create a tryte from three trits.

Arguments

• trits - Array of 3 trits [t0, t1, t2] where t0 is least significant

Examples

use trit_vsa::{Tryte3, Trit};

let t = Tryte3::from_trits([Trit::P, Trit::Z, Trit::N]);
// Value = 1 + 0*3 + (-1)*9 = 1 - 9 = -8
assert_eq!(t.value(), -8);

pub fn value(self) -> i32

Get the integer value of the tryte.

pub fn to_trits(self) -> [Trit; 3]

Extract the three trits.

Returns

Array [t0, t1, t2] where t0 is least significant.

pub fn get_trit(self, index: usize) -> Trit

Get a specific trit by index.

Arguments

• index - Trit index (0, 1, or 2)

Panics

Panics if index >= 3.

pub const fn zero() -> Self

Create a zero tryte.

pub fn is_zero(self) -> bool

Check if the tryte is zero.

pub const fn raw(self) -> u8

Get the raw packed representation.

Trait Implementations

impl Add for Tryte3

fn add(self, other: Self) -> Self::Output

Add two trytes, returning (result, carry).

type Output = (Tryte3, Trit)

The resulting type after applying the + operator.

impl Clone for Tryte3

fn clone(&self) -> Tryte3

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Tryte3

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

Formats the value using the given formatter.

impl Default for Tryte3

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Tryte3

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Tryte3

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

Formats the value using the given formatter.

impl From<Tryte3> for i32

fn from(tryte: Tryte3) -> Self

Converts to this type from the input type.

impl Hash for Tryte3

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 Mul for Tryte3

fn mul(self, other: Self) -> Self::Output

Multiply two trytes, returning (low, high) result.

The full result is low + high * 27.

type Output = (Tryte3, Tryte3)

The resulting type after applying the * operator.

impl Neg for Tryte3

type Output = Tryte3

The resulting type after applying the - operator.

fn neg(self) -> Self::Output

Performs the unary - operation.

impl PartialEq for Tryte3

fn eq(&self, other: &Tryte3) -> 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 Serialize for Tryte3

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<i32> for Tryte3

type Error = TernaryError

The type returned in the event of a conversion error.

fn try_from(value: i32) -> Result<Self>

Performs the conversion.

impl Copy for Tryte3

impl Eq for Tryte3
