Crate balanced_ternary 

A balanced ternary data structure.

A Ternary object in this module represents a number in the balanced ternary numeral system. Balanced ternary is a non-standard positional numeral system that uses three digits: {-1, 0, +1} represented here as Neg for -1, Zero for 0, and Pos for +1. It is useful in some domains of computer science and mathematics due to its arithmetic properties and representation symmetry.

Data Structures

• Digit Enum: Represents a single digit for balanced ternary values, with possible values:
  • Neg for -1
  • Zero for 0
  • Pos for +1

Features

All features are enabled by default.

To enable only some features, use the default-features option in your dependency declaration:

[dependencies.balanced-ternary]
version = "*.*"
default-features = false
 
# Choose which one to enable
features = ["ternary-string", "tryte", "ternary-store"]

Featureless

Without any feature, this library provide the type Digit and all its operations and the trait DigitOperate.

ternary-string

Add the structure Ternary which is a vector of Digits and a lot of utilities to manipulate digits into the ternary number. Implements DigitOperate.

tryte

Needs the feature ternary-string.

Add the type Tryte<N> which is a fixed size copy-type ternary number. Implements DigitOperate.

ternary-store

Needs the feature ternary-string.

Add structures to store ternaries efficiently. These types are provided:

• DataTernary: a variable length ternary number stored into TritsChunks,
• TritsChunk: a fixed size copy-type 5 digits stored into one byte,
• Ter40: a fixed size copy-type 40 digits stored into one 64 bits integer. Implements DigitOperate.

Structs

DataTernary

Offers a compact structure to store a ternary number.

ParseTernaryError

Error returned when parsing a string into a Ternary fails.

Ter40

A struct to store 40 ternary digits (~63.398 bits) value into one i64.

Ternary

Represents a balanced ternary number using a sequence of Digits.

TritsChunk

A struct to store 5 ternary digits (~7.8 bits) value into one byte.

Tryte

The Tryte<S> struct represents a Copy type balanced ternary number with exactly S digits (6 by default). Each digit in a balanced ternary system can have one of three values: -1, 0, or 1.
