Enum SystemDataContract 

#[repr(u8)]
pub enum SystemDataContract {
    Withdrawals = 0,
    MasternodeRewards = 1,
    FeatureFlags = 2,
    DPNS = 3,
    Dashpay = 4,
    WalletUtils = 5,

}

Variants

Withdrawals = 0

MasternodeRewards = 1

FeatureFlags = 2

Reserved slot — the feature-flags contract was never deployed at genesis and its implementation has been removed. The discriminant 2 is kept to preserve the stable numbering of subsequent variants.

DPNS = 3

Dashpay = 4

WalletUtils = 5

TokenHistory = 6

KeywordSearch = 7

DocumentHistory = 8

AppConnect = 9

ModerationCharters = 10

The charters of elected moderation teams (protocol version 14). Registered from protocol version 14 on: registered at genesis by chains born at 14 and inserted by the upgrade to 14.

Implementations

impl SystemDataContract

pub const ALL: [SystemDataContract; 11]

Every system data contract, including the reserved FeatureFlags slot.

Deliberately kept beside the enum so that adding a variant and adding it here are the same edit. assert_every_variant_is_listed below makes that mechanical rather than remembered: a new variant makes its match non-exhaustive and the crate stops compiling.

pub fn id(&self) -> Identifier

A new variant must also be added to SystemDataContract::ALL; this match is where the compiler stops you, but it cannot check that list for you.

pub fn source( self, platform_version: &PlatformVersion, ) -> Result<DataContractSource, Error>

Returns DataContractSource

Trait Implementations

impl Clone for SystemDataContract

fn clone(&self) -> SystemDataContract

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SystemDataContract

impl Debug for SystemDataContract

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

Formats the value using the given formatter.

impl Eq for SystemDataContract

impl Hash for SystemDataContract

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 Ord for SystemDataContract

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

fn eq(&self, other: &SystemDataContract) -> bool

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for SystemDataContract

fn partial_cmp(&self, other: &SystemDataContract) -> 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.
