Struct Committee 

pub struct Committee {
    pub validators: BTreeMap<ValidatorPublicKey, ValidatorState>,
    /* private fields */
}

Fields

validators: BTreeMap<ValidatorPublicKey, ValidatorState>

The validators in the committee.

Implementations

impl Committee

pub fn new( validators: BTreeMap<ValidatorPublicKey, ValidatorState>, policy: ResourceControlPolicy, ) -> Result<Self, ArithmeticError>

Creates a new committee from the given validators and resource control policy.

pub fn make_simple(keys: Vec<(ValidatorPublicKey, AccountPublicKey)>) -> Self

pub fn quorum_threshold(&self) -> u64

Returns the number of votes required to reach a quorum.

pub fn validity_threshold(&self) -> u64

Returns the number of votes required to reach the validity threshold.

pub fn validators(&self) -> &BTreeMap<ValidatorPublicKey, ValidatorState>

Returns the validators in this committee, keyed by their public key.

pub fn validator_addresses( &self, ) -> impl Iterator<Item = (ValidatorPublicKey, &str)>

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Committee

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

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for Committee

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

impl InputType for Committee

type RawValueType = Committee

The raw type used for validator.

fn type_name() -> Cow<'static, str>

Type the name.

fn create_type_info(registry: &mut Registry) -> String

Create type information in the registry and return qualified typename.

fn parse(value: Option<Value>) -> InputValueResult<Self>

Parse from Value. None represents undefined.

fn to_value(&self) -> Value

Convert to a Value for introspection.

fn as_raw_value(&self) -> Option<&Self::RawValueType>

Returns a reference to the raw value.

fn qualified_type_name() -> String

impl OutputType for Committee

fn type_name() -> Cow<'static, str>

Type the name.

fn create_type_info(registry: &mut Registry) -> String

impl PartialEq for Committee

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

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