Struct App

pub struct App {
    pub tag: char,
    pub identity: B32,
    pub vk: B32,
}

App represents an application that can be used to create, transform or destroy charms (tokens, NFTs and other instances of app data).

An app is identified by a single character tag, a 32-byte identity and a 32-byte vk (verification key). The tag is a single character that represents the type of the app, with two special values:

• TOKEN (tag t) for tokens,
• NFT (tag n) for NFTs.

Other values of tag are perfectly legal. The above ones are special: tokens and NFTs can be transferred without providing the app’s implementation (RISC-V binary).

The vk is a 32-byte byte string (hash) that is used to verify proofs that the app’s contract is satisfied (against the certain transaction, additional public input and private input).

The identity is a 32-byte byte string (hash) that uniquely identifies the app among other apps implemented using the same code.

Fields

tag: char

identity: B32

vk: B32

Trait Implementations

impl Clone for App

fn clone(&self) -> App

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for App

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

Formats the value using the given formatter.

impl Default for App

fn default() -> App

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for App

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for App

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

Formats the value using the given formatter.

impl Ord for App

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

Restrict a value to a certain interval.

impl PartialEq for App

fn eq(&self, other: &App) -> 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 PartialOrd for App

fn partial_cmp(&self, other: &App) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for App

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for App

impl StructuralPartialEq for App
