1//! Core type definitions for the [Sui] blockchain.
2//!
3//! [Sui] is a next-generation smart contract platform with high throughput, low latency, and an
4//! asset-oriented programming model powered by the Move programming language. This crate provides
5//! type definitions for working with the data that makes up the [Sui] blockchain.

9//! # Feature flags
10//!
11//! This library uses a set of [feature flags] to reduce the number of dependencies and amount of
12//! compiled code. By default, no features are enabled which allows one to enable a subset
13//! specifically for their use case. Below is a list of the available feature flags.
14//!
15//! - `serde`: Enables support for serializing and deserializing types to/from BCS utilizing [serde]
16//!   library.
17//! - `rand`: Enables support for generating random instances of a number of types via the [rand]
18//!   library.
19//! - `hash`: Enables support for hashing, which is required for deriving addresses and calculating
20//!   digests for various types.
21//! - `proptest`: Enables support for the [proptest] library by providing implementations of
22//!   [proptest::arbitrary::Arbitrary] for many types.

30//! # BCS
31//!
32//! [BCS] is the serialization format used to represent the state of the blockchain and is used
33//! extensively throughout the Sui ecosystem. In particular the BCS format is leveraged because it
34//! _"guarantees canonical serialization, meaning that for any given data type, there is a
35//! one-to-one correspondence between in-memory values and valid byte representations."_ One
36//! benefit of this property of having a canonical serialized representation is to allow different
37//! entities in the ecosystem to all agree on how a particular type should be interpreted and more
38//! importantly define a deterministic representation for hashing and signing.
39//!
40//! This library strives to guarantee that the types defined are fully BCS-compatible with the data
41//! that the network produces. The one caveat to this would be that as the Sui protocol evolves,
42//! new type variants are added and older versions of this library may not support those newly
43//! added variants. The expectation is that the most recent release of this library will support
44//! new variants and types as they are released to Sui's `testnet` network.
45//!
46//! See the documentation for the various types defined by this crate for a specification of their
47//! BCS serialized representation which will be defined using ABNF notation as described by
48//! [RFC-5234]. In addition to the format itself, some types have an extra layer of verification
49//! and may impose additional restrictions on valid byte representations above and beyond those
50//! already provided by BCS. In these instances the documentation for those types will clearly
51//! specify these additional restrictions.
52//!
53//! Here are some common rules:
54//!
55//! ```text
56//! ; --- BCS Value ---
57//! bcs-value           = bcs-struct / bcs-enum / bcs-length-prefixed / bcs-fixed-length
58//! bcs-length-prefixed = bytes / string / vector / option
59//! bcs-fixed-length    = u8 / u16 / u32 / u64 / u128 /
60//!                       i8 / i16 / i32 / i64 / i128 /
61//!                       boolean
62//! bcs-struct          = *bcs-value                ; Sequence of serialized fields
63//! bcs-enum            = uleb128-index bcs-value   ; Enum index and associated value
64//!
65//! ; --- Length-prefixed types ---
66//! bytes           = uleb128 *OCTET          ; Raw bytes of the specified length
67//! string          = uleb128 *OCTET          ; valid utf8 string of the specified length
68//! vector          = uleb128 *bcs-value      ; Length-prefixed list of values
69//! option          = %x00 / (%x01 bcs-value) ; optional value
70//!
71//! ; --- Fixed-length types ---
72//! u8          = OCTET                     ; 1-byte unsigned integer
73//! u16         = 2OCTET                    ; 2-byte unsigned integer, little-endian
74//! u32         = 4OCTET                    ; 4-byte unsigned integer, little-endian
75//! u64         = 8OCTET                    ; 8-byte unsigned integer, little-endian
76//! u128        = 16OCTET                   ; 16-byte unsigned integer, little-endian
77//! i8          = OCTET                     ; 1-byte signed integer
78//! i16         = 2OCTET                    ; 2-byte signed integer, little-endian
79//! i32         = 4OCTET                    ; 4-byte signed integer, little-endian
80//! i64         = 8OCTET                    ; 8-byte signed integer, little-endian
81//! i128        = 16OCTET                   ; 16-byte signed integer, little-endian
82//! boolean     = %x00 / %x01               ; Boolean: 0 = false, 1 = true
83//! array       = *(bcs-value)              ; Fixed-length array
84//!
85//! ; --- ULEB128 definition ---
86//! uleb128         = 1*5uleb128-byte       ; Variable-length ULEB128 encoding
87//! uleb128-byte    = %x00-7F / %x80-FF     ; ULEB128 continuation rules
88//! uleb128-index   = uleb128               ; ULEB128-encoded variant index
