Enum Round 

pub enum Round {
    Fast,
    MultiLeader(u32),
    SingleLeader(u32),
    Validator(u32),
}

An identifier for successive attempts to decide a value in a consensus protocol.

Variants

Fast

The initial fast round.

MultiLeader(u32)

The N-th multi-leader round.

SingleLeader(u32)

The N-th single-leader round.

Validator(u32)

The N-th round where the validators rotate as leaders.

Implementations

impl Round

pub fn is_multi_leader(&self) -> bool

pub fn multi_leader(&self) -> Option<u32>

Returns the round number if this is a multi-leader round, None otherwise.

pub fn is_fast(&self) -> bool

Whether the round is the fast round.

pub fn number(&self) -> u32

The index of a round amongst the rounds of the same category.

pub fn type_name(&self) -> &'static str

The category of the round as a string.

impl InputType for Round

type RawValueType = Round

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 Ord for Round

fn cmp(&self, other: &Round) -> 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 OutputType for Round

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

Type the name.

Resolve an output value to async_graphql::Value.

fn qualified_type_name() -> String

Qualified typename.

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

Introspection type name

impl PartialEq for Round

fn eq(&self, other: &Round) -> 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 Round

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

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

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

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.

fn to_value(&self) -> Value

Convert the scalar to Value.

fn is_valid(_value: &ConstValue) -> bool

Checks for a valid scalar value.

impl Serialize for Round

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,
