Struct linera_execution::ChainOwnership

pub struct ChainOwnership {
    pub super_owners: BTreeMap<Owner, PublicKey>,
    pub owners: BTreeMap<Owner, (PublicKey, u64)>,
    pub multi_leader_rounds: u32,
    pub timeout_config: TimeoutConfig,
}

Represents the owner(s) of a chain.

Fields

super_owners: BTreeMap<Owner, PublicKey>

Super owners can propose fast blocks in the first round, and regular blocks in any round.

owners: BTreeMap<Owner, (PublicKey, u64)>

The regular owners, with their weights that determine how often they are round leader.

multi_leader_rounds: u32

The number of initial rounds after 0 in which all owners are allowed to propose blocks.

timeout_config: TimeoutConfig

The timeout configuration: how long fast, multi-leader and single-leader rounds last.

impl Debug for ChainOwnership

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

Formats the value using the given formatter.

impl Default for ChainOwnership

fn default() -> ChainOwnership

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ChainOwnership

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for ChainOwnership

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 InputType for ChainOwnership

type RawValueType = ChainOwnership

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

Qualified typename.

impl OutputType for ChainOwnership

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 resolve<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, _: &'life1 ContextSelectionSet<'life2>, _field: &'life3 Positioned<Field> ) -> Pin<Box<dyn Future<Output = ServerResult<Value>> + Send + 'async_trait>>

fn qualified_type_name() -> String

Qualified typename.

fn introspection_type_name(&self) -> Cow<'static, str>

Introspection type name

impl PartialEq for ChainOwnership

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl ScalarType for ChainOwnership

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

Parse a scalar value.

fn to_value(&self) -> Value

Convert the scalar to Value.

fn is_valid(_value: &ConstValue) -> bool

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 ChainOwnership
